Ming-Pang Chung, I-Ching Wang, Hsun-Liang Chan, Hom-Lay Wang
PURPOSE: The primary aim of this study was to evaluate the buccal bone concavity position and depth in the anterior maxilla. The accuracy of cone beam computed tomography (CBCT) to measure the buccal bone concavity was also investigated. MATERIAL AND METHODS: Eleven fresh cadaver heads were used in this study. CBCT images were first acquired, on which the location and depth of the buccal bone concavity were measured in maxillary incisors and canines. After full-thickness mucoperiosteal flap reflection, the corresponding measurements were made directly on cadavers...

PURPOSE: The aim of this retrospective study was to evaluate the incidence of inferior alveolar nerve (IAN) lesion and duration of sensitivity disturbances after the insertion of dental implants. METHODS: One thousand sixty-five patients (mean age: 58.9 years) enrolled between February 2004 and July 2015 with partial or full mandibular edentulism were selected to receive dental implants for oral rehabilitation. A total of 3025 implants were placed. After surgical procedures, controls were scheduled at suture removal, that is, 10 days after surgery, and repeated at intervals of 1, 3, and 6 months, and comprised patient interview, clinical examination, and sensitivity tests...

OBJECTIVE: To evaluate clinically and radiographically, in humans, the healing of maxillary third molars postextraction sockets after application of different ridge preservation techniques 3 months after tooth extraction. MATERIALS AND METHODS: Twenty-six sockets (13 patients) were randomly assigned to 4 treatment modalities: deproteinized bovine bone mineral with 10% collagen (DBBM-C), poly(D,L-lactide-co-glycolide) with hydroxyapatite/β-TCP scaffold (PLGA/HA), PLGA/HA/β-TCP with 2...

BACKGROUND: Posterior maxillary tooth loss may complicate the implant treatment due to the alterations in alveolar anatomy and maxillary sinus pneumatization. This study aimed to comprehensively examine the anatomical structure of this region from cone-beam computed tomography (CBCT) images. MATERIALS AND METHODS: The posterior maxilla regions with single tooth loss were analyzed by dividing the variables into 3 subgroups from images of 597 patients chosen from 1160 CBCTs...

The fracture of dental implants is a rare occurrence in clinical settings. Possible causes of implant fracture include design or production flaws, overloaded occlusion force, implant location, metal fatigue, and bone resorption around the implant. This study reports on the successful removal and reimplantation of fractured implants.

PURPOSE: The objective of this study was to compare the implant stability and osseointegration of implants using a flap or flapless technique. MATERIAL AND METHODS: Mandibular premolars and molars were extracted from both sides in 6 dogs. After 8 weeks, 4 fixtures were implanted using either a flap or flapless technique. Implant stability quotient was measured on insertion and at 2, 4, and 8 weeks later. The animals were killed while the tissues were histologically analyzed...

The presence of the additional mental foramen of the mandible is considered to be a rare anatomical occurrence. Only a few cases have been reported. In these cases, only 1 foramen is called the mental foramen and the others are termed either accessory mental foramen or accessory buccal foramen. The purpose of this article was to present a case with computed tomography images and suggest that preoperative cone beam computed tomography should be performed to detect any anatomical variation. In addition, we present all reasonable terminology to ease the communication through unique terminology among surgeons...

PURPOSE: To evaluate the effect of blasting and bonding on abutment surface to prevent screw loosening in Morse taper connections. MATERIAL AND METHODS: Twenty-eight Morse taper connection implants were divided into 4 groups: no treatment (G1), blasting (G2), bonding (G3), and blasting + bonding (G4). In groups G2 and G4, the abutments were blasted with aluminum oxide granules; in groups G3 and G4, the conical abutment region was covered with a thin layer of bond thread lock agent...

OBJECTIVE: The aim of this systematic review and meta-analysis was to evaluate the role of osteogenic coatings (placement of a thin film of organic and inorganic osteoinductive and osteoproliferative materials) on implant surfaces in augmenting bone-to-implant contact (BIC) in osteoporotic bone. DATA SOURCES: To answer the focused question "Do osteogenic coatings on implant surfaces increase BIC in osteoporotic bone?" PubMed/MEDLINE, EMBASE, ISI Web of Knowledge, Scopus, and Google-Scholar databases were searched till June 2017 using different combinations of the following key words: bone-to-implant contact, coating, implant surface, osseointegration, and osteoporosis...

PURPOSE: The etiology and progression of periimplant mucogingival defects are multifactorial. As such, the aim of this study was to discern and discuss the key long-term prognostic factors that change the balance of homeostasis/regeneration in periimplant mucogingival and recession defects. MATERIALS AND METHODS: This report provides cases and a discussion of anatomical factors that affect the long-term maintenance of periimplant soft tissue. RESULTS: The factors guiding long-term maintenance of the periimplant soft tissue apparatus are increasingly complex due to the additive combination of patient-related factors, anatomical variations, and unique material-host interactions...

INTRODUCTION: Patient anatomy, practitioner experience, and surgical approach are all factors that influence implant accuracy. However, the relative importance of each factor is poorly understood. The present study aimed to identify which factors most critically determine implant accuracy to aid the practitioner in case selection for guided versus freehand surgery. METHODS: One practitioner's ideal implant angulation and position was compared with his achieved position radiographically for 450 implants placed using a conventional freehand method...

PURPOSE: To compare the long-term clinical and radiographic outcomes between immediate loading (IL) and conventional loading of implants placed immediately in fresh extraction sockets. MATERIALS AND METHODS: Demographic data, implant details, and periapical radiographs of patients were collected. The long-term marginal bone level remodeling and implant survival rate were calculated. RESULTS: Twenty-one patients (mean age 52.55 ± 14.61 years) with 35 implants immediately inserted into postextraction sites (22 immediate loaded and 13 delayed loaded) were analyzed...

PURPOSE: Zygomatic implants are becoming an ideal therapy with advanced implant-supported prosthetic treatment for the posterior atrophic maxilla. The purpose of this study is to examine the quantity and distribution of stress, which was caused by zygomatic implants placed using intrasinus method with or without augmentation to the atrophic posterior maxilla. MATERIALS & METHODS: In this study, 3-dimensional atrophic edentulous maxilla models with and without sinus augmentation are designed with computer-aided programs...

PURPOSE: This study evaluates the synergistic effect of serial application of bone morphogenetic protein 2 (BMP2) and fibroblast growth factor 2 (FGF2) on both new bone formation and periodontal tissue regeneration using 1-wall intrabony defect in mongrel dogs. MATERIALS AND METHODS: One-wall defects were created at the mesial aspect of the mandibular first molars of 6 male mongrel dogs. Each mandibular defect received 1 of the 2 experimental treatments randomly (BMP2 or BMP2 + FGF2), and it was allowed to heal for either 4 or 8 weeks postoperatively...

PURPOSE: The aim of this study was to clinically, radiologically, and histologically evaluate a sinus augmentation technique using a resorbable collagen sponge to maintain space between the Schneiderian membrane and the residual crestal bone. MATERIALS AND METHODS: Patients with partially edentulous maxillae were clinically and radiographically evaluated for implant placement. A total of 10 consecutive patients with the bone height for implant placement (<4.0 mm) were enrolled in the study...

PURPOSE: The aim of this study was to compare marginal bone loss around early-loaded SLA and SLActive tissue-level implants (Straumann Dental Implants; Institut Straumann AG, Basel, Switzerland) after a mean of 81-month follow-up period. MATERIAL AND METHODS: One hundred seven SLA and 68 SLActive implants were placed in 55 patients and loaded with final restoration after 8 and 3 weeks of healing time, respectively. Marginal bone loss around implants was determined radiographically at initial and after a mean observation time ranging between 20 and 81 months...
