Bonding of fractured permanent central incisor crown following radiographic localization of the tooth fragment in the lower lip: a case report

DENTAL TRAUMATOLOGY, Issue 5 2010
Gabriela Ferrari Da Silva Schwengber
The trauma also resulted in a cut on his mentum. Radiographic examination revealed the fractured tooth fragment embedded in the lower lip. The fractured tooth, with incomplete root formation, was treated endodontically and received a temporary restoration. After 15 days, the temporary restoration was removed and the fractured tooth fragment was etched with 37% phosphoric acid. A bonding system was then applied to the etched-fractured tooth surface without polymerization. The same bonding procedure was carried out on the tooth fragment. A layer of flowable resin composite was applied to the fragment, which was positioned on the remaining tooth. The resin composite was then polymerized, finished, and polished. [source]

Predictable management of cracked teeth with reversible pulpitis

AUSTRALIAN DENTAL JOURNAL, Issue 4 2009
P Abbott
Abstract Background:, The aims of this study were to assess symptoms and signs caused by cracks in teeth and to assess a conservative management protocol. Methods:, The symptoms and signs of 100 consecutive teeth that had reversible pulpitis associated with cracks were compared to findings from other reports. Teeth were managed with a conservative protocol which involved removal of cracks, caries and restorations, followed by placement of a sedative lining and interim restoration unless there were pulp exposures or insufficient tooth structure remaining. Teeth were monitored for pulp healing after three months and for up to five years. Results:, Eighty teeth did not require endodontic treatment. One tooth had an uncertain pulp status at review appointments. Fifteen teeth required endodontic treatment at the initial appointment because of carious pulp exposures (4 teeth), cracks extending into the pulp (2), and posts required (9). Four other teeth required endodontic treatment later following conservative pulp treatment due to continued pulpitis under the temporary restoration (1), pulpitis after core restoration (2), and pulp necrosis diagnosed at the review (1). Conclusions:, Provided there is an accurate diagnosis of the pulp status and its cause, teeth with reversible pulpitis due to cracks can be treated conservatively without endodontic treatment in about 80 per cent of cases.

Immediate and early non-occlusal loading of Straumann implants with a chemically modified surface (SLActive) in the posterior mandible and maxilla: interim results from a prospective multicenter randomized-controlled study

CLINICAL ORAL IMPLANTS RESEARCH, Issue 5 2008

Abstract Objective: Immediate and early loading of dental implants can simplify treatment and increase overall patient satisfaction. The purpose of this 3-year prospective randomized-controlled multicenter study was to assess the differences in survival rates and bone level changes between immediately and early-loaded implants with a new chemically modified surface (SLActive). This investigation shows interim results obtained after 5 months. Material and methods: Patients ,18 years of age missing at least one tooth in the posterior maxilla or mandible were enrolled in the study. Following implant placement, patients received a temporary restoration either on the day of surgery (immediate loading) or 28,34 days after surgery (early loading); restorations consisted of single crowns or two to four unit fixed dental prostheses. Permanent restorations were placed 20,23 weeks following surgery. The primary efficacy variable was change in bone level (assessed by standardized radiographs) from baseline to 5 months; secondary variables included implant survival and success rates. Results: A total of 266 patients were enrolled (118 males and 148 females), and a total of 383 implants were placed (197 and 186 in the immediate and early loading groups, respectively). Mean patient age was 46.3±12.8 years. After 5 months, implant survival rates were 98% in the immediate group and 97% in the early group. Mean bone level change from baseline was 0.81±0.89 mm in the immediate group and 0.56±0.73 mm in the early group (P<0.05). Statistical analysis revealed a significant center effect (P<0.0001) and a significant treatment × center interaction (P=0.008). Conclusions: The results suggested that Straumann implants with an SLActive can be used predictably in time-critical (early or immediate) loading treatment protocols when appropriate patient selection criteria are observed. The mean bone level changes observed from baseline to 5 months (0.56 and 0.81 mm) corresponded to physiological observations from other studies, i.e., were not clinically significant. The presence of a significant center effect and treatment × center interaction indicated that the differences in bone level changes between the two groups were center dependent. [source]

Immediate non-occlusal vs. early loading of dental implants in partially edentulous patients: a multicentre randomized clinical trial.

CLINICAL ORAL IMPLANTS RESEARCH, Issue 6 2008
Peri-implant bone, soft-tissue levels
Abstract Objectives: To compare peri-implant bone and soft-tissue levels of immediately non-occlusally loaded vs. non-submerged early loaded implants in partially edentulous patients up to 14 months after placement. Material and methods: Fifty-two patients were randomized in five Italian private practices: 25 in the immediately loaded group and 27 in the early loaded group. To be immediately loaded, single implants had to be inserted with a torque of ,30 N cm, and splinted implants with a torque of ,20 N cm. Immediately loaded implants were provided with non-occluding temporary restorations within 48 h. After 2 months, the provisional restorations were placed in full occlusion. Implants were early loaded after 2 months. Final restorations were provided 8 months after placement. Blinded assessors evaluated peri-implant bone and soft-tissue levels. Results: Fifty-two implants were immediately loaded and 52 were early loaded. No drop-out occurred. One single immediately loaded implant failed 2 months after placement. Both groups gradually lost peri-implant bone in a highly statistically significant manner at 2, 8, and 14 months. After 14 months, patients of both groups lost an average of 1.1 mm of peri-implant bone. There were no statistically significant differences between the two loading strategies for peri-implant bone and soft-tissue level changes (P>0.05). After 14 months, the position of the soft tissues did not change significantly from baseline (delivery of the final restorations 8 months after placement). Conclusions: There were no statistically or clinically significant differences between immediate and early loading of dental implants with regard to peri-implant bone and soft-tissue levels as evaluated in the present study.
