摘要:

AbstractSurgical repositioning of the dento‐skeletal components of the lower third of face, combined with appropriate orthodontic treatment, can be used to improve function and aesthetics. However, the attainment of three‐dimensional stability following corrective jaw surgery continues to be a major problem in the post‐surgical period.This paper examines the short‐term (6 week postoperative) and long‐term (12 months postoperative) horizontal skeletal stability of bilateral sagittal split mandibular advancement in 15 patients. The mean horizontal advancement of the mandible was 6.1 mm. Six weeks later, a mean continued forward movement of 0.16 mm was identified. The mean relapse at long‐term follow‐up was 0.46 mm (7.5%). Results indicate that rigid bicortical screw fixation of bilateral sagittal split osteotomies undertaken to correct horizontal lower dentofacial deficiency is both statistically and surgically predictable and stable when reviewed up to twelve months

摘要:

AbstractIn vitrostudies and early clinical trials have shown promising results for Delmopinol HCl solution as an effective mouth rinse for reducing experimentally induced gingivitis in the absence of mechanical plaque control. The efficacy of Decapinol mouthwash 2 mg/mL (Delmopinol HCl) in preventing gingivitis in a double‐blind, randomized clinical study with parallel group design was studied. Forty‐seven healthy young adults were randomly assigned to the Delmopinol or placebo groups. After an initial period of four weeks of intensive oral hygiene including biweekly professional cleaning of the teeth and oral hygiene instruction, all subjects achieved a low degree of gingivitis or a plaque score close to zero. At baseline, Bleeding on Probing, Modified Gingival Index and Plaque Index were recorded and the teeth were professionally cleaned. All forms of plaque control were then suspended and subjects were supervised in a one‐minute rinsing of Decapinol mouthwash 2 mg/mL or placebo twice daily. Measurements of efficacy variables were then repeated after two and three weeks treatment and adverse events were recorded. After the study period of three weeks all previous plaque control measures were resumed. At week four, all subjects were reassessed for the resolution of gingival inflammation and where residual gingival inflammation persisted, appropriate treatment was given. Only mild and short‐lasting adverse events were noted for the use of Delmopinol in the study period. However, for all teeth sites measured, significant differences between Delmopinol and placebo groups were found in Bleeding on Probing (p<0.05) and Plaque Index (p<0.0005). The difference was also significant for Modified Gingival Index on the buccal sites (p = 0.04). It can be concluded that 0.2% Delmopinol HCl used as a mouth rinse twice daily is effective in preventing the accumulation of dental plaque on tooth surfaces and the onset of gin

摘要:

AbstractSupernumerary teeth are relatively common in the maxillary incisor and molar areas. However, bilateral ectopic, fully erupted supernumerary mesiodentes are relatively rare. The present case documents a patient with localized periodontitis of the maxillary first and second molars associated with bilaterally erupted supernumerary teeth located in proximity to the buccal embrasure space between the molars. Combined clinical data suggested that these ectopic mesiodentes predisposed or contributed to the development of localized periodontitis.

AbstractAn unusual case of ectodermal dysplasia is presented. Besides the main symptoms of ectodermal dysplasia, congenitally missing teeth and the impaction of all the other existing permanent teeth make this case interesting.

摘要:

AbstractPanoramic radiographs of 1834 patients older than 21 years were evaluated for the prevalence of impacted teeth at different ages. The frequency of impacted teeth by age was constant, that is, the presence of completely impacted teeth could not be related to age.The interrelationship between the angulation of impacted teeth and the existence of adjacent teeth was studied in individuals older than 61 years. The angulation of most of the completely impacted teeth in the upper‐third molar region was horizontal when adjacent teeth were not present, whereas impacted teeth in the upper‐third molar region showed vertical angulation when adjacent teeth were present, suggesting that vertically impacted teeth may become exposed by bone resorption or infection and should be removed. The angulation of impacted lower third molars was horizontal irrespective of the presence of adjacent teeth. It appears that the interrelationship between the angulation of completely impacted teeth and the presence of adjacent teeth is different between the upper and lower third molar regions. The angulation of completely impacted teeth and the presence of adjacent teeth should be included in those criteria which determine whether or not completely impacted teeth should be remo

摘要:

AbstractEctopic eruption of teeth can occur in a wide variety of sites. These include the mandibular condyle, coronoid process, palate, nasal cavity and maxillary sinus. While this process is unusual, the detection of a third molar in the maxillary antrum is extremely rare. A case is presented of ectopic eruption of a third molar in the left maxillary sinus of a 35‐year‐old caucasian male giving rise to local morbid

摘要:

AbstractOcclusal reconstruction of both arches was performed using splinted implant crown pairs. Each pair of crowns was luted to parallel implant abutment pairs and these were screwed and glued into approximately parallel pairs of implant bodies. Paralleling of holes for implant body pairs was performed using a precision guiding device.

摘要:

AbstractThe necessary improvement of the bonding of denture teeth to the base resin has been hampered by inconsistent results and the consequent lack of clear guidance as to the best procedure to use. This state of affairs is in part due to poor experimental design. The tensile strength of notched planar interfaces between acrylic denture tooth material and cold‐cured acrylic resin was determined for various treatments under a protocol designed to minimize spurious failures. The tooth material treatment consisting of grinding and exposure to a methyl methacrylate‐trichloromethane mixture was, of those treatments, the most reliable in that no interfacial failures were observed. Strength was indistinguishable from that of both tooth and base acrylic under the same conditi
