the effect of inter-implant distance on retention and resistance of implant-tissue-supported overdentures is lacking in the literature. an in vitro study was performed to evaluate this effect for mandibular implant-tissue-supported overdentures retained by two ball attachments.an acrylic cast of an edentulous mandible was fabricated. three pairs of implants were symmetrically placed at both sid...

results the mean distances between the crestal bone and the implant shoulder in group 1 were 1.01, 1.44, and 1.93 mm at the implant placement time, and at the 6 and 12-month postoperative intervals, respectively. in group 2, these distances were 1.35, 1.20, and 1.41 mm, respectively. there were no significant differences in the marginal bone resorption between the two groups (p > 0.05). conclus...

PURPOSE Template-guided implant therapy has developed hand-in-hand with computed tomography (CT) to improve the accuracy of implant surgery and future prosthodontic treatment. In our present study, the accuracy and causative factors for computer-assisted implant surgery were assessed to further validate the stable clinical application of this technique. MATERIALS AND METHODS A total of 102 im...

OBJECTIVE The main goal of this study was to evaluate differences in stress distribution relevant to the number of implants under an anterior bridge when combined with a removable partial denture in the posterior region. MATERIALS AND METHODS Four three-dimensional finite element models (3D FEM) were designed from a mandible containing an implant-supported bridge extending between canines, an...

Surgical correction of hallux limitus or degenerative articular disease of the first metatarsophalangeal joint (MPJ), whether as singular conditions or in the face of concomitant hallux abducto valgus, is a dilemma with which foot surgeons have struggled with for almost a century. The ideal procedure would provide adequate pain-free motion of the first MPJ without shortening the hallux or unwei...

crestal bone loss is a biological complication in implant dentistry. the aim of this study was to compare the effect of progressive and conventional loading on crestal bone height and bone density around single osseointegrated implants in the posterior maxilla by a longitudinal radiographic assessment technique.twenty micro thread implants were placed in 10 patients (two implants per patient). ...

BACKGROUND Adverse local tissue reaction (ALTR) is characterized by periprosthetic soft tissue inflammation composed of a mixed inflammatory cell infiltrate, extensive soft tissue necrosis, and vascular changes. Multiple hip implant classes have been reported to result in ALTR, and clinical differences may represent variation in the soft tissue response at the cellular and tissue levels. The pu...

STATEMENT OF PROBLEM The identification of dental implant bodies in patients without available records is a considerable problem due to increased patient mobility and to the large number of implant systems with different designs. PURPOSE The purpose of this study was to document features that would help dentists identify non-threaded implant bodies from their radiographic images. MATERIAL A...
