OBJECTIVE This case report describes the clinical and surgical management of a patient with a unilateral alveolar cleft and associated extremely atrophied totally edentulous maxilla. METHOD Two zygomatic implants and four endosseous oral implants were placed under general anesthesia in a compromised maxilla to rehabilitate a 33-year-old patient with cleft lip and palate. The two specially des...

Primary angle closure glaucoma is one of the leading causes of blindness in Asia. Surgical intervention is often needed to control the intraocular pressure for patients with advanced glaucoma. The current surgical modalities include laser peripheral iridoplasty, lens extraction, trabeculectomy, goniosynechialysis, combined procedures, glaucoma implants, and cyclodestruction. The choice of surgi...

Three groups of chronic, skull-anchored, percutaneous implants differing in materials, design and surgical procedures used for implantation, were tested in macaque monkeys in conjunction with studies of an inner ear stimulation device. Implants from the first two groups in which high-speed drilling methods and stainless steel materials were used, showed a high percentage of failures during the ...

More than twenty years ago, hydroxyapatite (HA), calcium phosphate ceramics, was introduced as a coating for cementless hip prostheses. The choice of this ceramic is due to its composition being similar to organic apatite bone crystals. This ceramic is biocompatible, bioactive, and osteoconductive. These qualities facilitate the primary stability and osseointegration of implants. Our surgical e...

Over the last years, growing attention has been paid to the several domestic implant systems. This study presents results of a clinical trial of Implantium® implants followed up to 22 months. Two hundred fifty-two Implantium® implants were investigated which were placed in 119 patients between June 2003 and November 2004. The average follow-up period from implant placement was 10. 9months(SD 4....

PURPOSE The purpose of this study was to evaluate the osseointegration of calcium phosphate (CaP)-coated implants by ion beam assisted deposition with a lack of primary stability. METHODS A total of 20 CaP-coated implants were bilaterally placed in the mandible of five dogs. In the rotational implant group, the implants were inserted in oversized drilled sockets without mechanical engagement,...

INTRODUCTION: Orthopaedic prostheses implantation is an invasive surgical procedure, with an increased risk for post-operative infections. Since the life span and quality of these implants is improving and more prostheses are implanted every year, the incidence of post-operative infections will increase. Most implants are based on titanium or nickel-chromemolybdenum alloys, while their overall ...

Objectives: A variation on the usual maxillary sinus grafting technique and its results are presented, using a more conservative approach that provides better conditions for applying the graft in complicated situations. Material and Methods: Ten case reports are presented in which the multiple access technique was used due to the existence of large maxillary sinuses, where a wide surgical appro...

The conventional placement protocol for submerged and non-submerged implants was proposed in the 1960s and 1970s. Multicenter studies have reported satisfactory success rates for both protocols and a similar loss of crestal peri-implant bone after implant loading (0.5 to 1.5 mm). In recent years, placement of submerged implants using a single surgical procedure was introduced, with the immediat...
