The evaluation of the relationship between loading time and crestal bone loss around dental implants 12 months after loading was the objective of this study. All clinical and radiological data of patients treated with posterior mandibular implant-supported fixed dentures between January 4, 2013 and January 3, 2018 were retrieved from the archives. Loading time was recorded as the time between dental implant insertion and loading of the implant-supported restoration. The crestal bone levels of distal and mesial aspects of all implants were measured at postloading 12 months control evaluation on panoramic radiographs. Distal and mesial crestal bone loss values were recorded and averaged to obtain one mean value. The relationship between loading time and crestal bone loss was evaluated with statistical analysis. A total of 89 patients and 238 implants were included in the study. The loading time for each implant was recorded between a range of 0 and 401 days. A linear relationship was observed between loading time and crestal bone loss measured at 12 months control evaluation. The crestal bone loss at 12 months control evaluation after loading was significantly increased with the increase in the loading time after dental implantation (p less then 0.05). The range of CBL was narrower between 100 and 200 days of loading time. The increase in loading time may cause increased crestal bone loss after 12 months function. Crestal bone loss at 12 months control evaluation is more predictable in dental implants loaded between 3 to 6 months after dental implant placement.In the present scenario, dental implants have proven to be a very reliable and popular treatment option for partial and completely edentulous arches. The biological, chemical, local, clinician, and implant related factors determine sequence of bone turnover that eventually enhances the success of implant therapy. The positioning of implant is followed by an inflammatory process that results in de novo bone formation and deposition on the implant surface. Pure titanium is commercially the prime material of choice for an implant. The implant surface can be chemically altered by a change in manufacturing, finishing, thermal treatment, blasting etching, coatings, and even sterilization procedures. These techniques have led to major innovations in implant dentistry as they roughen the surface, promoting bone deposition and stability. The current paper gives a comprehensive review of the diverse topographical characteristics of an implant surface and the altered techniques offered to create appropriate roughness to enhance osseointegration starting from fundamental to the latest techniques.We analyzed 2,861 uncemented primary total hip arthroplasties (THAs) with ceramic on ceramic bearing couple (C on C) for dysplastic hips followed up at least one year. The age at THA was 58 and the follow-up period was 6.8 (maximum of 21.4) years. Those belonged to Crowe's classification I were 76.4%, II were 14.6%, III were 7.0%, and IV were 2.0%. Two types of C on C were used alumina on alumina (A on A) for 1979 hips and zirconia toughened alumina on zirconia toughened alumina (ZTA on ZTA) for 882 hips. Osteolysis was not detected. Dislocation occurred in six (0.2%) hips and the prevalence did not differ between A on A and ZTA on ZTA. Two liner fractures occurred only in A on A. Joint noise was detected in 79 (2.8%) hips. The prevalence of the noise was lower in ZTA on ZTA than in A on A. GSK2643943A The revision rate was 0.5% and had no difference between A on A and ZTA on ZTA. All revisions in ZTA on ZTA were performed early after the initial surgery, while there was only one early revision in A on A. Taking endpoint as revision for any reason, the final survival rate was 97.2% for all C on C. At nine years after THA, the survival rate was higher in A on A than in ZTA on ZTA. Preventing the early failure by careful surgical procedure is essential to expect the same long-term durability of ZTA on ZTA as that of A on A.Open calcaneal fractures with extensive bone loss and severe soft tissues injuries are very rare. There is no treatment protocol for these severe injuries. The incidence of infection, osteomyelitis, and amputation is high compared to closed calcaneal fractures. An independent prognostic factor for increased complications is the high type of fracture according to Gustillo and Anderson's classification. A one-stage or two-stage procedure with open reduction and internal fixation, external fixation, percutaneous pinning, minimally invasive procedures, and subtalar arthrodesis are treatment options. We present a case of open type IIIB fracture of the calcaneus with extensive bone loss managed with a two-stage procedure. First, a cement spacer was inserted to fill the void and then, after the soft tissue envelope had healed with no sign of infection, a three-dimensional (3D) printed custom-made calcaneus implant was inserted. This is the first report in the literature of using a 3D custom-made calcaneal implant for a severe open calcaneal fracture with extensive osseous defect. At one-year follow-up, plain radiographs of the foot showed the calcaneus implant in place. The American Orthopedic Foot and Ankle score (AOFAS) was 76, and the patient had mild restrictions to his daily activities due to mild heel pain.This study evaluates the success of dental implants placed in the maxillary posterior region and whether an association exists regarding length and implant success. Dental implants are a surgical component that interfaces with jaw bone to support dental prostheses. In 1978, Brandmarks presented a two-stage threaded titanium root-form implant that has become the best-maintained dental implant. Differences in anatomy make treatment for posterior quadrants more challenging than that for anterior quadrants. The need for dental implants includes partial/complete edentulousness, tooth loss during a mixed dentition period, and immediate replacement due to trauma. This retrospective study was conducted as an institutional setting, and all patients undergoing implant surgery in the maxillary posterior region were considered. We performed Excel tabulation and data analysis using Statistical Package for the Social Sciences (IBM, Armonk, NY). Results show that posterior maxilla bone height was greater in females than males.
