objectives: implant primary stability is one of the important factors in achieving implant success. the osteotome technique may improve primary stability in patients with poor bone quality. the aim of this study was to compare implant stability using two different techniques namely osteotome versus conventional drilling in the posterior maxilla. materials and methods: in this controlled randomi...

peri-implantitis is a state defined as an inflammatory reaction around osseointegrated implants, leading to progressive loss of supporting bone. various treatment methods are suggested in the treatment of peri-implantitis and clinicians have to choose a method over a large number of treatment protocols. lasers have shown promising therapeutic effect in treatment of peri-implantitis. however, so...

conclusions there are few absolute contraindications for di treatment. as a whole, correct patient selection, and applying standard rules of surgical procedure and di loading would lead to a successful di treatment. results though, there are multiple technique-related or patient-related local and systemic factors, which may interfere with proper osseointegration or compromise the long-term impl...

purpose: to present our experience with cyanoacrylate tissue adhesive in eyes with exposed hydroxyapatite orbital implants. methods: cyanoacrylate tissue adhesive was used in 3 patients with hydroxyapatite orbital implant exposure defects. results: cyanoacrylate glue was applied on the defective area of 3 patients presenting with small exposure (<4mm). the patients were followed for 33 months (...

background : the number of children with cochlear implants who have other difficulties such as attention deficiency and cerebral palsy has increased dramatically. despite the need for information on the results of cochlear implantation in this group, the available literature is extremely limited. we, therefore, sought to compare the levels of auditory perception in children with cochlear implan...

objective: low quality of the bone and insufficient bone due to the size of the sinus and resorption of the alveolar ridge decrease the long-term survival of implants in the posterior maxilla compared to other regions of the jaws. surgical procedures to increase bone volume make it possible to place implants longer than 8 mm. in this situation sinus elevation makes it possible to place implants...

titanium (ti) is one of the most widely used biomaterials for manufacturing dental implants. the implant surface properties strongly influence osseointegration. the aim of the present study was to in vitro investigate the characteristics of ti dental implants in terms of mutagenicity, hemocompatibility, biocompatibility, osteoinductivity and biological safety. the ames test was used to test the...

pre-implant disease is an inflammatory process that affects the surrounding tissues of a functional osseointegrated implant. it is usually the result of a disequilibrium between the micro-flora and the defense system. this case reports a 57-year-old man with unusual bone loss around dental implants. this was an unusual case of peri-implantitis that occurred only in the implants on one side of t...
