Effects of periodontal support and fixed splinting on load transfer by removable partial dentures.

STATEMENT OF PROBLEM: Periodontally compromised abutment teeth complicate the design of bilateral distal extension removable partial dentures. PURPOSE: This study investigated the stress induced in the remaining oral structures by a bilateral distal extension I-bar-retained RPD with periodontally involved abutments in a photoelastic simulation model. MATERIAL AND METHODS: Composite photoelastic models were used as a simulation model in determining the stress generating characteristics of I-bar RPDs with varying degrees of periodontal involvement of the distal abutments. Effects of fixed splinting were considered. RESULTS AND CONCLUSIONS: Under the same load conditions, the highest stresses developed in the model with the largest osseous defect. Increasing the number of splinted teeth did not provide a proportional decrease in maximum stress levels. The more severe the osseous defect, the greater assistance was provided by splinting to periodontally sound teeth. This simulation study suggests that routine cross-arch splinting may not be appropriate.

[Direct application of fiber-reinforced composites in splinting in a case of periodontitis. II].

Attachment loss through advanced periodontitis results in tooth mobility, and then loss of teeth. To prevent progression it is needed to eliminate any exciting agent and correct functional disorders in consequence of disease. Regeneration of periodontium is impossible and mastication is difficult because of tooth mobility. Long-term maintenance of mobile teeth is doubtful. We have to prevent the extraction of these teeth to stabilise them by a splint made of material that is inexpensive, reparable, provides sufficient support for the artificial tooth. Fiber-Reinforced Composite (FRC) fulfills the above requirements. In their case-reports the authors demonstrate the practical application of splinting with FRC materials. In these cases the FRC splints are not only periodontal splints but they act as orthodontic retainers or supports for an artificial tooth.

Mechanical interactions of an implant/tooth-supported system under different periodontal supports and number of splinted teeth with rigid and non-rigid connections.

OBJECTIVES: This study investigated the mechanical interactions of implant-teeth splinting systems under different periodontal supports and number of splinted teeth with rigid and non-rigid connectors using non-linear finite element (FE) approach. METHODS: Two FE models with normal and compromised periodontal supports containing a Frialit-2 implant splinted to the first and second premolars were constructed. Non-linear contact elements were used to simulate a realistic interface fixation within the implant system and the sliding function of the non-rigid connector. ANOVA was used to test for relative importance of the investigated factors and main effects for each level of the three investigated factors (periodontal supports, teeth splinting and connector designs) in terms of the stress values were performed. RESULTS: The simulated results indicated that the cross-interaction of the periodontal support and the splinting situation was a major factor affecting the stress value in alveolar bone. An additional splinting decreased the stress values of bone significantly for a compromised periodontal support. The individual factor of periodontal support also influenced the stress found in the alveolar bone (28%) and implant (72%), and the stress values increased when the periodontal support was reduced. Using different connectors affected the stresses found in bone (15%), implant (21%) and prosthesis (99%). The stress values of the implant and prosthesis increased, but were decreased in bone when the splinting system used non-rigid connectors. The mobility of natural teeth and the implant system between non-rigid and rigid connections showed only small differences. CONCLUSIONS: A non-rigid connector should be used with caution since it breaks the stress transfer and increases the unfavorable stress values in the implant system and prosthesis. The tooth/implant-supported system with an additional splinting is more efficient in compromised periodontal supports.

The reaction of the periodontium to different types of splints. (II). Histological aspects.

To study the influence of splints on periodontal tissues, Obwegeser and Merkx splints were applied to beagles. Histological evaluation was performed after splinting periods of 48 h and 6 weeks. After 48 h, gingivitis had developed when using both types of splints. After 6 weeks, the adverse effects of the splints were more predominant. Gingivitis had become severe and mild periodonitis had developed. In the case of Merkx splints, the periodontal ligament appeared to be somewhat less affected but the condition of the gingiva appeared to be somewhat worse than in the case with Obwegeser splints. For both types of splints, it is important that clinical application should be attended by measures not only to reduce plaque accumulation, but also to minimize trauma due to their application and continuous mechanical irritation of the tissues.

[Use of intracoronal splints in therapy of periodontal disease].

The study concerns the evaluation of the efficacy of intracoronal composite splints (ICS) in the therapy of periodontal disease in its full clinical state. Maxillar and mandibular front teeth were splinted over the period of 12 weeks as a part of a complex therapy procedure of developed periodontal disease. The results of the therapy were evaluated using periodontal indexes, parameters for oral hygiene and other relevant clinical parameters. Values were processed with Student's t-test. With the use of ICS very good results in the therapy of periodontal disease in a short period of time were obtained. Parameter values decreased, especially the index of tooth mobility: before therapy by 2.84 and after therapy to 1.12. Intracoronal composite splints, in comparison with other type of splinting, satisfy both functional and aesthetic aspects.
