AIM To use multilevel, multivariate models to analyze factors that may affect bone alterations during healing after an implant immediately placed into an extraction socket. MATERIAL AND METHODS Data included in the current analysis were obtained from a clinical trial in which a series of measurements were performed to characterize the extraction site immediately after implant installation and...

BACKGROUND The incidence of dry mouth and its public health impact are increasing as the result of a progressively larger, medicated older population and because chronic diseases, like periodontitis, are prevalent pathologies among elderly patients. Periodontitis and continuous remodeling and rebuilding alveolar processes greatly affect the margin of the alveolar bone, and there is evidence ind...

PURPOSE The purpose of this study was to evaluate the soft tissue and bone change around two adjacent implants in one-stage implant surgery. METHODS Eleven subjects (7 males, 4 females) who were needed placement of 2 adjacent implants in the molar area were included. The two implants were placed with the platform at the level of the alveolar crest. The interproximal bone between the 2 implant...

A long-term denture wearer exhibited advanced alveolar bone loss, resulting in an atrophic mandible. Symphyseal bone height was 10 mm. The inferior alveolar nerve and mental foramen were close to the crest of the mandible. The symphyseal region was available for endosteal implant placement. Patient was an 83-year-old white male who was medically compromised. Anticoagulant therapy was stopped an...

Alveolar cleft reconstruction is a major challenge in cleft lip and/or palate (CLP) patients and golden standard protocol is to perform bone grafting (BG) before canine eruption and subsequent orthodontic closure. Objective of this study was to compare the post operative morbidity of two procedures in terms of complications i.e. the average operation time, intra-operative blood loss, postoperat...

BACKGROUND Osteoporosis is an age-related metabolic bone disease characterized by decreased mass and increased susceptibility to fracture. The literature suggests a relationship between oral bone loss and skeletal osteoporosis; however, most studies have produced conflicting results. The purpose of this study was to determine if a relationship exists among alveolar bone loss, alveolar bone dens...

BACKGROUND Guided bone regeneration (GBR) is a widely used procedure for augmenting alveolar ridge width prior to placement of endosseous implants. Various graft materials and barrier membranes (non-resorbable and bioabsorbable) have been used in GBR. The aim of this study was to assess the performance of a new bioabsorbable, synthetic polyglycolic acid/trimethylene carbonate (PGA/TMC) barrier ...

discussion this segmental ridge-split procedure with gradual bone expansion provides a quicker method wherein an atrophic ridge can be predictably expanded and eliminating the need for a second surgical site. this technique also shows that immediate implantation in split ridge of mandible can be performed. introduction narrow alveolar ridges especially in posterior mandibular remains a serious ...

The aim of the present study was to assess the efficacy of a ready-to-use injectable bone substitute on the prevention of alveolar ridge resorption after tooth extraction. Maxillary and mandibular premolars were extracted from 3 Beagle dogs with preservation of alveolar bone. Thereafter, distal sockets were filled with an injectable bone substitute (IBS), obtained by combining a polymer solutio...

The objective of this study was to compare the alveolar bone growth in the 2 sides of the maxillary sinus after bilateral sinus lift procedures were performed with the simultaneous placement of dental implants in 20 consecutive patients. After elevation of the Schneiderian membrane, one side had only platelet-rich plasma (PRP) gel applied, while the other had placed only alloplastic graft mater...
