    Жалобы потребителей, связанные со стоматологическими имплантатами, поступившие от стоматологов и хирургов во всем мире, были проанализированы производителем имплантатов в течение определенного периода. Частота «жалоб, связанных с имплантатами»по сравнению с«количеством проданных имплантатов» показывает, что имплантаты с полированной эндооссальной поверхностью, предназначенные для протоколов немедленной нагрузки, а также одиночные имплантаты вызывают существенно меньше жалоб клиентов по сравнению с традиционными 2-этапнымисистемами (р<0,001) с грубой поверхностью (пескоструйная обработка/ протравка) (р<0,001) и большим эндооссальным диаметром. Поскольку мы планировали опубликовать эти данные и собирали их тщательным образом, данное исследование является перспективным.

    Customer complaints regarding dental implants stemming from dentists and surgeons world-wide were analyzed for a defined period by an implant manufacturer. The number of “complaints related to implants” vs. “implants sold” reveals that implant with polished endosseous surface and designed for immediate loading protocols as well as single piece implants are significantly less prone to customer complaints compared to traditional 2-stage systems (p < .001) with rough (sand-blasted/acid etched) surface (p < .001) and larger endosseous diameter. As we had planned to publish these data and collected them meticulously, this study is prospective.

    Diese prospektive klinische Studie untersuchte die Verweil- und Erfolgsquote von 66 Titanimplantaten nach 5 Jahren. Alle Implantate wurden in Knochenregionen eingesetzt, die zuvor mit Autotransplantaten und nicht resorbierbaren Barrieremembranen augmentiert worden waren. 3 Patienten mit 5 Implantaten absolvierten die Studie nicht. Keines der 61 auswertbaren Implantate ging im Studienzeitraum verloren (Verweilquote: 100 %). An 1 Implantat war eine periimplantäre Infektion zu verzeichnen. Die anderen 60 Implantate wurden nach 5 Jahren als klinischer Erfolg gewertet. Die Erfolgsquote nach 5 Jahren betrug somit 98,3 %. Die Autoren folgerten, dass Implantate in regenerierten Knochenregionen vergleichbar gut abschneiden wie Implantate in nicht regenerierten Knochenregionen.

    Dental implants are considered nowadays by most of clinicians and patients as the first line of treatment in restoring missing teeth. The prognosis of dental implants has become very good, and minimal postoperative complications are found. In a scenario where teeth were lost due to advanced periodontal disease insufficient bone is found in the in the involved areas. This will influence the esthetics, and the long term prognosis of dental implants. In such cases dental implant therapy is not an option without additional bone augmentation or sinus lifting. Augmentation and sinus lifting procedures are possible and well established, but they usually increase the overall treatment risk, the number of necessary operations as well as the cost of the treatment significantly. Basal screw implants offer today an alternative treatment. They anchor in stable, resorption free bone areas. Cortical engagement of these endosseous implants allow treatment in immediate load protocol and they avoid peri-implantitis.

    Immediate loading today is a widely accepted practice all over the world. It is the treatment of choice for most implantologists. Especially with highly retentive macro thread designs and use of cortical anchorage, using single piece implants for this treatment modality is very reliable. The main risk to an immediately loaded implant is overloading of bone during the first weeks of the bone healing. Splinting helps preventing micro movement and distributes forces between multiple imlpants. This article describes the use of Syn-Crystallisation phenomenon used for Intra-Oral-Welding. Titanium bars are used to splint multiple implants in a passive manner, thereby providing high primary stability to the implants throughout the healing phase.

    This article describes the treatment steps to resolve a case of conventional dental implant failure with the help of basal implants and conventional bridges. By utilizing the remaining corticals (lingual, vestibular, basal) immediate implant treatment was possible, although a large vertical bone groove had been developing due to the failure of three implants on the right mandible of the patient. Due to the usage of basal implant, bone augmentations and healing (waiting-) times were avoided.

    This article describes problems which occurred with a specific type of lateral basal and crestal implants and analyses a number of likely causes of their failure. The implants under discussion here were made from a PEEK-compound (Polyetheretherketone/ BaS04 6 %). According to our analysis the failures are closely connected to the design of the implants, combined with the specific choice of the implant material and mistakes in the clinical application of the implants and the prosthetics. Keywords: Basal implants, modified PEEKcompound, iso-elastic design of dental implants, immediate loading, osseo-integration.

    In the aim of achieving an optimal esthetic result, implant dentistry has become a prosthetically driven procedure. So special care is being taken to focus on the details that would lead to this objective. These details may include imitating the natural teeth, by harmonizing the structures around the placed implant. The prosthetic and/or surgical parts of the procedure should be performed to reach an optimal outcome. In order to minimize the resorption of hard and soft tissue, that occurs after extractions and in order to create a natural emergence profile of implant born prosthesis – a socket preservation procedures was used. However in case of severe ridge deficiencies, hard and soft tissue augmentation procedures are indicated. In this paper we will present a case report using a new approach in socket ridge preservation, which is the socket shield technique (partial root retention).

    The posterior maxilla until today presents a challenging site for implant placement. Treatment with conventional techniques is often impossible.The area of poor bone quality is typically combined with reduced bone height. Nevertheless 90 % of the masticatory forces are to be met in the distal maxilla. Both tubero- pterygoid and bi-cortical maxillary implants are a good option to provide rigid support. The insertion of these devices offer resistance both against intrusive (Angle Class 1, Angle Class 2) and extrusive (Angle Class 3) forces. The placements of long and cortically anchored implants in distal maxilla have made dental implant protocols even in the atrophied maxilla predictable and easy. The purpose of this article is to describe and evaluate closely, the justification of implants in this area with regards to, anatomy, surgical technique, prosthodontic rehabilitation and potential complication.

    The article reports on a treatment attempt to resolve a situation after multiple dental implant losses in the severely resorbed maxilla. Modalities of the failed treatment and the new intervention are discussed. Screwable basal implants are suitable to equip the resorbed maxilla with endosseous anchorage points, however these implants require immediate splinting. They thereby allow immediate loading.

    Implant infection and periimplantitis are recurrent and serious problem in implantology. Multiple techniques have been discovered to prevent biofilm formation and avoid the failure of the implant in dental practice. We propose that use of NaCl solution as preservation medium for dental implants may be a simple and cost reductive method of avoiding implant contamination before implantation procedure. Four strains of health relevant micro-organism were used for testing the disinfection efficiency of various concentrations of NaCl solution. Freeze resistance of NaCl solution samples was tested at -19˚C. In Comparison group gamma-sterilization (25kGy) was applied. The results prove effectiveness of Gamma-sterilization technique; application of sodium chloride of physiologic concentrations for storage of bone dental implants is questionable. Application of NaCl in higher concentrations (8-9 %) seems to be a reasonable strategy for implant preservation and storage. Our data shows that it may be possible in the future to supply dental implants without them being radiated. This would save costs in production and allow a larger part of the population, to access dental implant treatment.

    Basal osseointegrated implants are inserted into the jawbone coming from their lateral aspect. Masticatory load transmission is confined to the horizontal implant segments and, essentially, to the cortical bone structures. Best implant sites are at the base of the heavily mineralized anterior corner of the ascending ramus. This site can be easily visualized radiographically: The Amber line, or linea obliqua. It is one of the advantages of basal implants, that even circular constructions in the mandible can be created. This is owed to the elasticity of the implants body, which compensates the mandibular flexion. Furthermore no grafting procedures are ever necessary in combination with basal implants. The thin vertical implant part avoids the development of infections. Over the years, based on clinical experience, a precise, fast, and inexpensive treatment procedure has been developed to optimize the implants, surgical technique, prosthetic rehabilitation and follow-up with BOI implants.

    Aims: Differences in basal dental implant stability with and without the use of cortical bone screws were investigated using the «Ostell»® device. Because the precision of the slot prepared into the bone depends on the surgeon’s skill (clean cut in one plane) and bone density (D1 to D4), the implant’s fit and primary stability differs. The study describes the increase of the implant’s stability after securing the implant with additional cortical bone screws and evaluates the change in the medium term stability of the secured implant.

    Using basal implants in many indications has become a standard procedure. Basal implants enable the surgeon to place implants in atrophied mandibles with osseo-integrated abutments and to equip them in an immediate load protocol. This way augmentations, bone transplants, distractions and similar additional operations are avoided. The posterior mandible presents often itself extremely atrophied. Implantologists trained in the usage of basal implants can choose between four different treatment procedures to equip this bone area with implants. The procedures are explained and compared to traditional treatment alternatives.

    The aim of this study was to investigate the effects of bone substitute materials on fibroblast cell lines in vitro. The materials included hydroxyl-apatite in different chemical compositions. Cellular responses for particulate hydroxyl-apatite (HA) have been determined by MTT-test and by cytometric quantification of fluorescein diacetate/ propidium iodide cell number. Differentiation properties of fibroblasts had been studied. It was found that there is no significant decrease in cell population after adding HA nanoparticles to the fibroblast cell line.

    The objective of this study was to evaluate the morphology and integration status of human retrieved basal implants. Three basal implants that were in function from 13 to 61 months were retrieved from patients due to prosthetic reasons. Following surgical removal, the samples remained in 10% buffered formaline for 7 days. Bone morphology was evaluated by transmitted and polarized light microscopy, and bone-to-implant contact (BIC) histomorphometric assessment was determined through computer software. The BIC for basal implants were significant higher (more than 77%) than in screw type implants. The strong and stable osseointegration of basal implants is a proved fact. Basal implants seam to meet the remodeling conditions of the bone in more natural less artificial way than crestal implants.

    This article reports on the implantological treatment in the atrophied lower jaw. To avoid augmentations and nevertheless equip the distal mandible with endosseous implants, we have used basal implants in such a way, that the base plates were positioned below the alveolar nerve in the region of the canines, and above the nerve distally to the area of the 2nd molar. All implants were immediately splinted and thereby loaded with a circular bridge. The aesthetical and functional outcome was satisfactory. By using this technique a secure distal bridge support is available for almost all patients. The placement of base-plates below the lower alveolar nerve is a useful technique.

    Patients suffering from edentulous posterior maxilla compromised by markedly reduced subantral bone height can now undergo an endosseous implant therapy thanks to sinus floor augmentation. Various techniques of sinus floor elevation have been reported, among which lateral window osteotomy is the most common. However, the presence of anatomical structures such as septum, sinus floor convolutions, sharp bony ledges or even thin bony projections, may lead to complications mostly reflected in membrane perforation. In order to overcome these obstacles, the use of CT scan prior to surgery helps determine the anatomical variations of maxillary sinus and relevant structures that enable surgeons to alter their intervention approach.

    For many patients removable upper dentures are acceptable, as long as it is possible to leave parts of the palatum free from an un-desireable denture plate and a long as the dentures are not overly mobile. When the last teeth are lost, the patients expect a fast solution, they try to avoid full dentures. They consider full dentures outdated. Dental implantology provides the desired solution. In the case shown here the residual teeth were extracted and replaced by basal implants. Both types of basal implants were used: lateral implants and screw-type implants. Due to the surface properties and the reduced diameter of the basal implants the extraction sockets could be equipped immediately after the extraction. The first fixed restauration was incorporated on day two after the operation. The use of basal implants with thin, polished vertical implant portions allows immediate reconstruction even after extractions and in unfavourable bone situations. Cortial bone areas may be reached with basal implants in several areas of the jaw bone.

    Immediate implant placement after tooth extraction is becoming a common procedure in implantsupported oral rehabilitation1. However, it must fulfill a series of conditions among which is the achievement of a good initial fixation known as “primary stability”. Normally, this anchorage is achieved by the presence of the residual bone beyond the apex of the extracted tooth (sub-apical bone) of which, 3mm to 5mm are required, as stated by some authors. However, in certain situations, it is not possible to go beyond the apex due to anatomical limitations (sinus floor, dental nerve…). Thus, clinicians are often faced with challenging decisions regarding the timing of implant placement; what would be the adequate approach to be adopted?

    Though failure rates of endosseous dental implants are relatively low, the increasing number of implant surgeries being performed worldwide is leading to a greater number of implant failures. This is creating a challenge for both the implantologist and the patient. Patients, who have been treated successfully with implants in the past, will likely select implants again in lieu of prostheses in the event of an implant failure. However, most patients do not understand, nor do they want to experience, the long waiting period necessary for returning to normal masticatory function after initiating the re-implantation process.

    Hydroxyapatite (HA) is the main component of bone. The bone grafting substitute described here consists of nanocrystalline HA embedded in a highly porous matrix of silica (SiO2) gel. This HA-silica-matrix is fully biodegradable and at the same time extremely osteoconductive. Ectopic bone formation was induced even when implanting the HA silica matrix subcutaneously into porcine fatty tissue thus proving osteoinductive properties.

    Immediate or early loading of dental implants has been a hot topic in implantology. It shortens the treatment time and makes it possible to provide the patient with a functional and aesthetic reconstruction during the entire treatment period. Given the desire to produce implants that can be safely administered in immediate loading protocols, some manufacturers are eager to produce implants or implant surfaces that promote faster healing. This article reviews previously published reports discussing primary stability which occurs with immediate implant placement and secondary stability which occurs after several months of osseointegration. The theoretical loss in stability that occurs between these two periods has been the focus of implant design and surface modifications in an attempt to facilitate increased stability during this period.

    The aim of this prospective clinical study was to evaluate the survival rates at 12 months of transmucosal implants placed in the posterior mandible and immediately restored with single crowns. MATERIALS AND METHODS: Thirty ITI dental implants with sandblasted, acid-etched surfaces were placed in 30 patients missing at least 1 mandibular molar and immediately restored if acceptable primary stability was attained. Primary stability was measured with resonance frequency analysis (RFA) using the Osstell device, and only implants with a stability quotient greater than 62 were included in the study. RFA measurement and radiographic assessment were made at baseline and 6 months after implant placement. Plaque Index, Bleeding Index, probing depth, attachment level, and width of keratinized tissue were measured at the 12 month follow-up examination. RESULTS: At 12 months, only 1 implant had been lost; it was removed because of acute infection. Radiographic as well as clinical examination confirmed osseointegration of all implants, with a survival rate of 96.7%.

    This prospective clinical study evaluated the 5-year survival and success rates of 66 titanium implants placed in bone that had been previously augmented with autografts and nonresorbable barrier membranes. During the observation period, three patients with five implants dropped out of the study. None of the remaining 61 implants were lost during the follow-up period (implant survival rate of 100%). One implant exhibited a periimplant infection, whereas 60 implants were considered clinically successful at the 5-year examination, resulting in a 5- year success rate of 98.3%. It was concluded that the clinical results of implants in regenerated bone are comparable to those of implants in nonregenerated bone.
