BACKGROUND The feasibility of implant treatment in patients after oral ablative tumor surgery and defect reconstruction has not yet been investigated in terms of the requisite high standards of success assessment. A report on this topic must address not only implant survival but implant health, bone response, soft tissue health, failure pattern, and time of failure, as well. METHODS From June...

OBJECTIVE To describe a technique for socket augmentation in molar extraction sockets with severe bone wall defect. METHODS Five teeth in four patients were included in this study. Each tooth had buccal and/ or lingual bone loss identified by bone sounding and periapical radiographs before removal. After a flapless, minimally invasive tooth extraction, the socket was grafted with deproteinize...

The use of acetabular cup revision arthroplasty is on the rise as demands for total hip arthroplasty, improved life expectancies, and the need for individual activity increase. For an acetabular cup revision to be successful, the cup should gain stable fixation within the remaining supportive bone of the acetabulum. Since the patient's remaining supportive acetabular bone stock plays an importa...

Insufficient bone volume is one of the major challenges encountered by dentists after dental implant placement. This study aimed to evaluate the efficacy of a customized three-dimensional polycaprolactone (3D PCL) scaffold implant fabricated with a 3D bio-printing system to facilitate rapid alveolar bone regeneration. Saddle-type bone defects were surgically created on the healed site after ext...

BACKGROUND Previous studies have shown that adequate thickness or initial augmentation of soft tissue has a positive effect on the stability of peri-implant bone. This randomized, controlled trial aimed to evaluate the influence of augmenting soft tissue with platelet-rich fibrin (PRF) on crestal bone and soft tissue around implants. METHODS After randomization, 31 fully threaded titanium imp...

objective: to determine the pattern of stability changes as a reflection of early healing around single-stage roughened-surface implants in humans utilizing resonance frequency analysis (rfa). materials and methods: hundred twenty-five patients who demanded dental implants were treated with two different implant (nobel biocare replacetm and strummantm iti) systems. bone type was classified into...

OBJECTIVE Lateral ridge augmentations are traditionally performed using autogenous bone grafts to support membranes for guided bone regeneration (GBR). The bone-harvesting procedure, however, is accompanied by considerable patient morbidity. AIM The aim of the present study was to test whether or not resorbable membranes and bone substitutes will lead to successful horizontal ridge augmentati...
