OBJECTIVES The aim of this histomorphometric prospective study was to ascertain the efficacy of phycogenic bone substitute in an augmented sinus. The process of graft healing, bone remodeling, and biomaterial replacement was examined. MATERIAL AND METHODS The phycogenic material (fluorohydroxyapatite) made from calcium-encrusted sea algae was used for the(More)
PURPOSE To analyze the vertical dimension of subsinus alveolar bone that is available for placement of endosseous implants. MATERIALS AND METHODS Subsinus alveolar bone height (SBH) was determined via radiographs and categorized into three groups: Group A corresponded to SBH < 5 mm; group B SBH of 5 to 9 mm; and group C, SBH > 9 mm. Statistical analysis(More)
An endosseous implant is described as osseointegrated when it is immobile in function. Objective measures of stability testing have been described. The Periotest is a commercially available device that is used for this purpose. This study was designed to measure stability of endosseous implants placed in the mandible. Implants were placed in the mandibular(More)
BACKGROUND The effect of hydroxyapatite coating of dental implants is controversial. The long-term fate of hydroxyapatite-coated implants has been the subject of some criticism. PURPOSE The aim of this retrospective study was to assess the clinical outcome of hydroxyapatite-coated cylindrical root-form endosseous Impladent dental implants (LASAK Ltd,(More)
Selective intraarterial neoadjuvant chemotherapy of carcinoma in the region of the lingual artery was performed in 23 patients (bilaterally in 4 patients). The superficial temporal artery (STA) was surgically exposed and a preshaped infusion catheter was inserted. The catheter tip was maneuvered through the STA into the lingual artery under fluoroscopic(More)
PURPOSE To compare the efficacy of 2 common materials in sinus augmentation surgery and to assess their contribution when enriched with autogenous bone. MATERIALS AND METHODS The prospective human study was performed in 48 sinus grafting operations using beta-tricalcium phosphate or deproteinized bovine bone (pure or mixed with 10% to 20% autogenous bone)(More)
This study was carried out to evaluate the prevalence of sinus mucosa perforation occurred during maxillary sinus mucosa elevation surgery, its relation to objective conditions and to the causative medical history, and its influence on postoperative sinusitis, as well. One hundred and forty-six sinus lift procedures have been evaluated in 118 patients. The(More)
Dental implants have been considered to be a successful treatment modality. Recently, achieving a good osseointegration is not the ultimate goal for the restorative dentist. Successful implant treatment demands the best gingival esthetic success along with stability and function of the implant. This study was performed to obtain answers to some(More)
During the sinus lift procedure, undesirable perforations of the Schneiderian membrane can occur in up to 58% of cases. Several methods for their closing exist. This article presents a method of covering the perforation with a strip of oxidized regenerated cellulose (Surgicel). One or two layers of material swell after being saturated with blood, turning(More)
Aesthetics in implantology is a topic currently attracting lot of attention from dental implantologists all over the world. It includes both white and red aesthetics with much greater importance been given to the red aesthetics. In this article, both hard tissue and soft tissue procedures and techniques, used in the development of implant recipient sites(More)
