To provide an anatomical basis for clinical implant esthetics, we evaluated the morphology of the nasopalatine canal (NPC) and analyzed labial and interproximal bone anatomy at the maxillary anterior region. We sought to investigate the effect of maxillary protrusion and tooth labiolingual inclination on labial bone anatomy in Chinese adults. Three dimensional (3D) images were reconstructed usi...

In 61 patients, 61 consecutive implants were placed immediately after extraction of one anterior or premolar maxillary tooth. One of 3 surgical approaches based on rotated full (RPF) or rotated split (RSPF) palatal flaps, with and without the use of barrier membranes to enable primary soft tissue closure, was applied. A bovine bone mineral graft was used in all cases. At the time of implant pla...

Spontaneous early exposure of submerged implants during the osseointegration healing phase may be a harmful factor that results in early crestal bone loss around the implants. The objective of this study was to assess the effect of spontaneous early exposure on crestal bone loss around submerged implants, with special attention given to the relationship between the degree of exposure and the am...

Management of internal root resorption is a challenge to the endodontists. If it is left untreated, it may lead to the destruction of the surrounding dental hard tissues. Despite, routine obturation techniques are often employed without considering the best technique to solve this problem. This study presented a case of internal root resorption and apical periodontitis affecting tooth 12 (FDI) ...

Advanced glycation end products (AGE) are formed in long-lived matrix proteins by a nonenzymatic reaction with sugar. The presence of AGE in beta 2-microglobulin-amyloid fibrils of dialysis-related amyloidosis, one of the characteristic features of which is an accelerated bone resorption around amyloid deposits, was recently demonstrated. This suggested a potential link of AGE in bone resorptio...

The development of implantology requires enough bone support, sufficient bone architecture. The use of autograft remains the gold standard; however the surgeons use cortical bone coming from mandibular part or craniofacial site, involving severe anaesthetic bone loss. The strategy of bone substitutes in place of autograft can be an efficient method. Several patients having a sinus lift augmenta...

Background Mandibular continuity defects occur after tumor resection, maxillofacial injury, or osteomyelitis. Despite the current availability of a plethora of treatment modalities, bone substitutes, and various clinical adjuncts, an exact reconstructive recapitulation of large bony defects continues to be beyond reach. In this clinical pilot study, we report a novel method for reconstruction ...

The first report in the literature to quantify early crestal bone loss was a 15-year retrospective study that evaluated implants placed in edentulous jaws. In this study, Adell et al. reported an average of 1.2 mm marginal bone loss from the first thread during healing and the first year after loading. In contrast with the bone loss during the first year, there was an average of only 0.1 mm bon...
