PURPOSE Unlike standard dental implants, the stabilization of orthodontic microscrews removed after treatment is done without osseointegration and achieved by several components: cortical bone thickness (CBT), microscrew geometry, and drilling depth. The purpose of this study was to evaluate 10 different microscrews and the influence of their geometric parameters with different CBT and drilling...

BACKGROUND Treatment of tibial stress fractures in elite dancers is centered on rest and activity modification. Surgical intervention in refractory cases has important implications affecting the dancers' careers. HYPOTHESIS Refractory tibial stress fractures in dancers can be treated successfully with drilling and bone grafting or intramedullary nailing. STUDY DESIGN Case series; Level of e...

OBJECTIVE To evaluate the outcome of ovarian needle drilling using transvaginal ultrasound guidance as an alternative to the traditional laparoscopic electrosurgical drilling for patients with polycystic ovary syndrome (PCOS). DESIGN A randomized controlled study. SETTING University teaching hospital and private practice setting. PATIENT(S) The study comprised 163 patients with clomiphene...

*Department of P.O.P, college of dentistry, university of Mosul, Mosul, Iraq. Introduction Conservation of anchorage in totality has been a perennial problem to the traditional orthodontist. Conventional means of supporting anchorage have been used by either intra oral sites or relying on extra oral means. Both of these have their limitations. The extra oral forces very difficult device and som...

The aim of this research was to develop an efficient and accurate method to fabricate a dental implant surgical guide. The surgical guide is adapted from the patient's vacuum-formed clear template with the use of a plate with three ceramic balls, a six-axis drilling machine and its fixture. The plate, with the ceramic balls used as radiographic markers, is glued to the template, and the patient...

OBJECTIVE Percutaneous cochlear implantation (PCI) surgery uses patient-specific customized microstereotactic frames to achieve a single drill-pass from the lateral skull to the cochlea, avoiding vital anatomy. We demonstrate the use of a specific microstereotactic frame, called a "microtable," to perform PCI surgery on cadaveric temporal bone specimens. STUDY DESIGN Feasibility study using c...

Rise in temperature is inevitable orthopaedic drilling. Massive research had beendone the field of drilling to investigate effect cutting conditions, bone relatedparameters, and drill bit geometric parameters on heat generation minimum surrounding tissuesinjury. In present research, contradictory conclusions regarding conditions bitgeometric were observed. Minimum 31°C was achieved at speed 186...
