Polyethylene ribbon and fixed orthodontic retention and porcelain veneers: solving an esthetic dilemma.

The patient, a 58-year-old woman, had started orthodontic treatment to correct spacing between the maxillary anterior teeth 6 year prior to presentation with a chief complaint of tooth discoloration and spacing. The treatment had consisted of the use of a removable appliance to retract the maxillary anterior teeth. The patient continued to wear the appliance sporadically. When she presented, the maxillary incisors were in primary occlusal trauma with Grade 2 mobility. The patient discontinued wearing the appliance. The periodontal condition was addressed with initial therapy. As part of the treatment plan to stabilize the maxillary anterior teeth and provide the patient with an esthetic result, it was decided to do a limited occlusal adjustment of the maxillary anterior teeth to control fremitus, and to place a fixed, composite resin, polyethylene ribbon-reinforced splint, using a facial approach. The esthetic restoration of these teeth was accomplished with bonded porcelain veneers.

In situ effect of 10% carbamide peroxide on resin-dentin bond strengths: a novel pilot study.

PURPOSE: This pilot study used a novel study design to evaluate the effect of a 10% carbamide peroxide bleaching gel on the bond strength of a resin-based composite system to dentin. MATERIALS AND METHODS: Dentin disks were obtained from human third molars, polished to 600 grit, and mounted on the palatal aspect of a removable orthodontic retainer. Two disks were exposed to a 10% carbamide peroxide bleaching gel for 2 h/d for 21 days, whereas two disks were not treated and served as controls. A retainer was worn by the participant regardless of whether bleaching was used, simulating the action of the saliva/oral fluids on the dentin specimens. After the treatment phase, the dentin disks were retrieved and a resin-based composite system was applied to the specimens following manufacturer's instructions. Composite dentin "sticks" were obtained and tested in microtensile mode. Bond strength values were obtained for treated (n = 20) versus nontreated (n = 26) dentin and were analyzed statistically. RESULTS: Mean bond strengths values (SD) were 29.9 MPa (6.2) and 39.2 MPa (5.8) for treated and nontreated dentin specimens, respectively (p < .001). CONCLUSION: The results of this study suggest that nightguard (home) bleaching with 10% carbamide peroxide for 2 h/d for 21 days significantly affects resin-dentin bond strengths when dentin is exposed to bleaching material. CLINICAL SIGNIFICANCE The findings of this novel pilot study imply that dentin bonding, such as to exposed root surfaces and cervical areas of the teeth, should not be performed immediately after bleaching with 10% carbamide peroxide.

Anterior crossbite correction in uncooperative or disabled children. Case reports.

Uncooperative or disabled children who present with an anterior crossbite provide the clinician with a challenge to use innovative strategies to attempt crossbite correction. The following case reports provide possible treatment strategies as well as showing some pitfalls in both diagnosis and treatment of anterior crossbites in this difficult to treat group of patients.

Class II/Division 2 malocclusion: a method of planning and treatment.

This paper presents a method of cephalometric treatment planning for Class II division 2 malocclusions. The method combines improvement in dental and facial aesthetics, with reduction in overbite and inter-incisor angle. An individual case is illustrated; examples of the appliances commonly used being shown in the treatment of an adolescent patient.

Rapid correction of anterior crossbite using a fixed appliance: a case report.

Anterior crossbite is a commonly encountered problem that is traditionally managed with removable appliances. This paper demonstrates some of the advantages of using fixed appliances to correct these malocclusions. In this case, treatment was completed more rapidly than would have occurred with conventional techniques.

Average arch widths and associated changes between initial, post-treatment and post-retention measurements.

Computer image monitoring was used for evaluation of dental arch changes. A new special device captured geometrically calibrated images permitting comparison of several different dental casts. In the first part of this study 792 sets of study casts were screened. Measurements of dental arch width between reference points of canines, first premolars and first molars were made: upper jaw: men: canines: 35.1 +/- 0.13 mm; first premolars: 37.5 +/- 0.13 mm; first molars: 48.1 +/- 0.19 mm; women: canines: 33.4 +/- 0.13 mm; first premolars: 35.6 +/- 0.15 mm; first molars: 46.7 +/- 0.19 mm. In the second part of the study, changes between initial, post-treatment and post-retention alignment (5-years after orthodontic therapy) of upper and lower dental arch of 36 subjects were analyzed. Upper and lower arch compression in first premolars and molars area was visible before treatment. We conclude that computer image monitoring can be used for evaluation of dental arch changes during the different steps of treatment.
