Many studies described several parameters which are supposed to determine success or failure in longterm evaluations of dental implants. However, the relationship between crestal bone loss around implants and the location of implant-abutment connection in the bone still needs further investigations.The subgingival microgap between the implant and the abutment, which creates higher bone level re...

PURPOSE To report the application of an electrical mallet (magnetic mallet) in osteotome-assisted surgery for sinus floor elevation with implants placed in fresh sockets and 2-year follow-up. MATERIALS AND METHODS A total of 32 patients (70 implants, 36 in the molar and 34 in the premolar regions) requiring extractions of maxillary premolars and molars were included in this prospective study....

OBJECTIVE to compare the soft and hard tissue healing and remodeling around tissue-level implants with different neck configurations after at least 1 year of functional loading. MATERIAL AND METHODS eighteen patients with multiple missing teeth in the posterior area received two implants inserted in the same sextant. One test (T) implant with a 1.8 mm turned neck and one control (C) implant w...

BACKGROUND Melatonin has many roles, including bone remodeling and osseointegration of dental implants. The topical application of melatonin facilitated bone regeneration in bone defects. We evaluated the effects of topical application of melatonin on vertical bone augmentation in rat calvaria secluded spaces. MATERIAL AND METHODS In total, 12 male Fischer rats were used and two plastic caps ...

We are currently developing a small perforated titanium subperiosteal implant specifically for orthodontic therapy, which can be placed anywhere on the bone surface. In the present study, we coated this implant with hydroxyapatite (HA) or alpha-tricalcium phosphate (alpha-TCP) in an attempt to shorten the initial stabilization period relative to the few months that is usually required. The coat...

AIM The aim of the present study was to assess the prevalence of subjects with progressive bone loss at implants with a function time of at least 5 years. MATERIAL AND METHODS Radiographs of 1346 patients who had attended annual follow-up visits at the Brånemark Clinic, Public Dental Services, Gothenburg, Sweden were retrieved. Six hundred and sixty-two subjects fulfilled the inclusion criter...

Purpose: The purpose of the present study was to investigate whether a fluoride modification of the titanium surface would have an effect on bone response after implantation. Materials and Methods: Titanium-oxide–blasted titanium implants with and without fluoride modification were investigated in a rabbit tibia model. Quantitative analysis of surface roughness, biomechanical interlocking, and ...

Bone growth into cementless prosthetic components is compromised by osteoporosis, by any gap between the implant and the bone, by micromotion, and after the revision of failed prostheses. Recombinant human transforming growth factor-beta 1 (rhTGF-beta 1) has recently been shown to be a potent stimulator of bone healing and bone formation in various models in vivo. We have investigated the poten...

Polyetheretherketone (PEEK) is considered a potential material for replacing traditional biomedical metals used in orthopedic implants because of its similar elastic modulus to human bone. However, the poor osteogenic activity PEEK itself hinders clinical application. In this study, surface was grafted with poly (sodium vinylsulfonate) through single-step ultraviolet-initiated graft polymerizat...

Background. It is important to understand the influence of different collar designs on peri-implant marginal bone loss, especially in the critical area. Objectives. The purpose of the present systematic review and meta-analysis was to compare dental implants with different collar surfaces, evaluating marginal bone loss and survival rates of implants. Methods. Eligibility criteria included clini...
