The design and fabrication of a segmented cast-metal resin-bonded splint.

This article describes a technique for splinting periodontally compromised teeth and for preventing orthodontically treated teeth from relapsing. The fabrication of a segmented cast-metal resin-bonded splint, with nonrigid connection of the splinted teeth, eliminates the many problems of a conventional multi-unit resin-bonded splint.

Presurgical prosthetic management of the periodontal patient--a modern adhesive approach.

The comprehensive management of the periodontal prosthetic patient requires that treatment be provided in a logical sequence; initial therapy, presurgical prosthetic management, surgical management of hard and soft tissue lesions, post-surgical prosthetics, followed by maintenance therapy. This article focuses on some of the most perplexing challenges encountered during the presurgical prosthetic management phase of periodontal diagnosis and therapy, including the stabilization of mobile teeth, the immediate replacement of teeth that require removal due to advanced attachment loss, and the correction of visual defects created by soft tissue loss. A number of creative treatment modalities are described that utilize silane-treated etched-glass fiber ropes and tapes (GlasSpan, GlasSpan, Inc.) for the internal reinforcement of periodontal splints and for the attachment of composite and natural tooth pontics as transitional tooth replacements. Gingival-colored composite (Gingiblend, Jeneric Pentron) and its importance as a diagnostic aid during the early stages of periodontal therapy and as an esthetic permanent restorative material are also examined.

Clinical use of an intraoral silicoating technique.

UNLABELLED: A ceramic fracture rate of metal-ceramic fixed prosthodontics of up to almost 9% calls for an efficient and effective intraoral repair system. For the repair of fractured veneering material, an intraoral silicoating technique was introduced. In contrast to other repair techniques, the silicoating can successfully be used on a variety of dental restorative materials and, therefore, offers additional applications in the field of the intraoral adhesive technique. This silicoating technique, consisting of a chairside airabrasion device filled with a specific silica-coated air-abrasion medium, has been used intraorally by the authors since 1993 for clinical purposes. The clinical procedure is described for different applications in the field of the adhesive technique: intraoral repair, preconditioning of core buildups, implant abutments, and surfaces of fixed prosthodontics for the bonding of orthodontic brackets or periodontal splints. CLINICAL SIGNIFICANCE: The intraoral silicoating technique promotes reliable adhesion to the major part of metal alloy, composite, and ceramic surfaces of fixed prosthodontics. Preliminary clinical results of intraoral repairs conducted with this technique have shown that it presents a medium-term alternative to the replacement of the restoration. Also, the preliminary results of the clinical applications in other fields of adhesive dentistry are promising.

Groove associated periodontitis: classification proposal and clinical. Case report.

The presence of a palatoradicular groove (PRG), more frequently observed at the level of the upper lateral incisors, may compromise both the radicular pulp and the periodontium leading to endodontic-periodontal lesions. Frequently, the prognosis of these elements is compromised because of the missed diagnosis or because of the complex therapeutic approach that is necessary to cure the associated pathologies. A histopathological and clinical classification is proposed showing according to the degree of the affected tooth involvement. Preventive measures are also discussed and a clinical case is reported. A 49-year-old woman presented with a PRG at the superior left lateral incisor, endodontically treated years before, associated with probing pocket depths of 10 mm and 7 mm, clinical attachment loss of 11 mm and first degree mobility. The tooth was treated with splinting, periodontal surgery with radiculoplasty, root surface conditioning, guided tissue regeneration and with a prosthetic crown for esthetic rehabilitation. Six years later, the operated site showed probing pocket depths of 3 mm, gains in clinical attachment level of 4 mm and 7 mm and reduction of tooth mobility. The ceramic crown re-established an acceptable esthetics for the patient. Even in the presence of a 3(rd) degree PRG, according to the classification presented, the prognosis of the tooth may be positive through the association of root canal treatment, periodontal and prosthetic therapy. The classification presented shows the clinician the best therapeutic approach.

[Sequelae of unsecured elastic bands (the status after 7 years)].

The use of elastic bands without an adequate appliance mechanism to close a diastema represents a professional error on behalf of the dentist. Two case reports are presented showing both the consequences of such malpractice and the successful periodontal and orthodontic treatment over a period of seven years. The reasons for this successful treatment are discussed as well as points of special interest.

Occlusal considerations in periodontics.

Periodontal disease does not directly affect the occluding surfaces of teeth, consequently some may find a section on periodontics a surprising inclusion. Trauma from the occlusion, however, has been linked with periodontal disease for many years. Karolyi published his pioneering paper, in 1901 'Beobachtungen uber Pyorrhoea alveolaris' (occlusal stress and 'alveolar pyorrhoea'). (1) However, despite extensive research over many decades, the role of occlusion in the aetiology and pathogenesis of inflammatory periodontitis is still not completely understood.

Photoelastic stress analysis in perforated (Rochette) resin bonded bridge design.

Rochette described the perforated cast metal bonded design for splinting periodontally compromised teeth. The design was later used for replacing missing teeth. The main causes of failure of the perforated (Rochette) type design were attributed to inappropriate case selection and erosion of the composite from perforations. The aim of this study was to analyse the effect of stress magnitude and direction on failure of perforated resin bonded bridges (RBBs). The objective was to compare stress magnitudes in this design with those reported on the non-perforated RBBs. Photoelastic modelling materials were selected to represent the relative stiffnesses of a posterior mandibular and an anterior maxillary perforated (Rochette) type design. The sizes of the models were scaled to x 2.5 in order to enhance visual analysis of the stress patterns. Stress magnitudes were quantified from isochromatic fringes and stress directions were evaluated from stress trajectories. These revealed a high-stress concentration around the perforations, particularly for those at the proximo-lingual/palatal (connector) areas. This experimental study revealed that the main reason for failure of Rochette designs is deformation at the perforations.

The influence of fiber reinforcement of composites on shear bond strengths to enamel.

STATEMENT OF PROBLEM: Fiber-reinforced composites (FRC) are used in direct intra-oral applications as periodontal splints and chairside tooth replacement by bonding them to etched enamel with resin adhesives and composites. There is little information regarding the effect of FRC on the shear bond strength of composite to etched enamel. PURPOSE: The purpose of this study was to examine the effect of resin preimpregnated and non-preimpregnated fiber-reinforced composites on enamel to composite shear bond strength (SBS). MATERIAL AND METHODS: Specimen groups (n = 12) consisted of a control (composite with no fiber reinforcement), Ribbond, Splint-It Unidirectional, Splint-It Woven, and Connect, which were bonded to 37% phosphoric acid etched Prime and Bond NT adhesive-treated bovine enamel surfaces on a bed of Tetric Flow composite. Specimens were thermocycled 1000 times between 5 degrees and 55 degrees C and loaded on a universal testing machine in shear at a linear increasing load until fracture (MPa). The fractured surfaces of the debonded specimens were evaluated to determine the nature of the fracture with a light binocular microscope (x10). Shear bond strength data were subjected to analysis of variance (ANOVA) and Student-Newman-Kuels tests (P <.05). RESULTS: Mean MPa +/- SD for the test groups were as follows: Control, 15.6 +/- 2.4; Splint-It Unidirectional, 15.3 +/- 2.4; Splint-It Woven, 16.5 +/- 1.8; Connect, 18.8 +/- 1.5; and Ribbond, 15.8 +/- 2.2. The Connect FRC group had significantly higher (P <0.05) enamel SBS than all other groups. Fracture analysis showed varying types of failures among the groups, with cohesive fractures within the fiber reinforcement of Splint-It Unidirectional and Connect, cohesive fractures within the bonding resin/flowable composite for Ribbond and the control, and adhesive fracture at the fiber reinforcement interface with Splint-It Woven. CONCLUSION: Within the limitations of this study, no differences in SBS were observed with the addition of 3 of the 4 FRCs compared to composite without FRC, with the exception of the Connect product which provided significantly higher SBS values.
