OBJECTIVE To determine by means of a systematic review the best treatment, whether interproximal wear or incisor extraction, to correct anterior lower crowding in Class I patients in permanent dentition. METHODS A literature review was conducted using MEDLINE, Scopus and Web of Science to retrieve studies published between January 1950 and October 2013. In selecting the sample, the following ...

Esthetics has become a major concern in periodontal plastic surgery and in restorative therapy. The reconstruction, in patients with a high lip line smile, of the lost interdental papilla in the esthetic zone, due to loss of periodontal support, periodontal disease or surgical pocket elimination in the esthetic zone is one of the most difficult goals for the practitioner. Restoring teeth in the...

JL he combination of acid-etching and bonding has led to dramatic changes in the practice of orthodontics. Newman began the revolution in orthodontics with the advent of epoxy-bonded attachments. Bonding has evolved and now is used for; placement of attachments, various types of retainers, and resin build-ups which address tooth size and shape problems encountered during orthodontic treatment. ...

OBJECTIVE To compare the interproximal soft tissue dimensions adjacent to single implant restorations in the premolar-molar position with those adjacent to the contra-lateral natural teeth. MATERIAL AND METHODS Twenty-five patients with a single-tooth implant in premolar-molar position and healthy contra-lateral teeth were enrolled in this retrospective cross-sectional study. The reason for t...

The modification of the col shape and position by the restorative alveolar interface technique (RAI) was studied in the interproximal areas between the mandibular first molars and fourth premolars of 10 dogs. Full thickness flaps were raised to expose the interproximal root surface and alveolar bone crest. The RAI procedure was performed only on the experimental sides and the control areas were...

BACKGROUND It has been reported that clinical results of mechanical periodontal treatment could differ between subjects and among different sites of the tooth in the patient. The objective of this multilevel analysis is to investigate clinical factors at subject and sites of the tooth that influence variations in clinical attachment (CAL) increase and probing depth (PD) diminution of adjunctive...

making impression to obtain an accurate working cast needs to use accurate impression materials such as polyether. on the other hand, polyether cannot be used easily in places with undercut such as excessive interproximal spaces and under the pontics of fixed partial dentures as it may be locked in these free spaces. in this article, a method is presented to blockout interproximal spaces in ord...
