[The effect of splints on the status of the hard dental tissues and periodontium in patients with jaw fractures].

Effects of metal splints on the hygienic status of the oral cavity and status of dental hard tissues and the periodontium were studied in 30 patients with fractures of the jaws during the first days after treatment with splints and in the postimmobilization period. Sixty-seventy days after the splints were removed, the hygienic status of the oral cavity was worse than in normal subjects; moreover, the intensity of caries increased and the periodontal status deteriorated.

Non-surgical treatment of sports-related temporomandibular joint disorders in basketball players.

In this study, 18 basketball players (11 female, seven male; age range 14-32 years) with temporomandibular joint (TMJ) problems who had a history of sport injuries related to head or jaw region were evaluated and the results of the treatment were presented. A standardized functional examination of the masticatory system was performed including measurement of maximal jaw movements, recording of joint sounds, pain on movement of the jaw as well as tenderness to palpation of the both TMJ or masticatory muscles. Patients were also evaluated periodontally. Diagnosis was made according the criteria, described by Okeson, and appropriate treatment was applied using different kind of splints. At the end of treatment only one patient continued with right TMJ reduction with slight pain. Except for that patient, none of the patients had pain after treatment. The maximum opening of the jaws and the maximal jaw movements were statistically increased after treatment. Patients with TMJ problems also showed periodontal problems, most likely due to inadequate oral hygiene because of the limited jaw movements and pain. Periodontal parameters including probing depth (PD), Plaque index (PI), and Sulcus Bleeding Index (SBI) improved after treatment. Sports-related TMJ injuries may result in complex problems such as pain, TMJ sounds, limitation in maximal jaw movements and maximum opening of the mouth, difficulty in chewing. With the appropriate diagnosis this could be treated non-surgically in 6-8 months. This study also showed that the TMJ disorders may cause periodontal problems, which may affect all teeth and also the general health of the athlete.

[Clinical evaluation of measuring system of occlusal force].

An occlusal diagnostic system was evaluated for clinical applications. This system consists of pressure sensitive sheets (DENTAL PRESCALE, Fuji Photo Film Co.) and analyzing computer (OCCLUZER FPD703, Fuji Photo Film Co.). The clinical efficiency of this system was evaluated in aged dentates, aged complete denture wearers and an aged patient suffered from periodontitis. The results were as follows: 1. There was a positive correlation between the masticatory efficiency and maximum occlusal force. 2. In the complete denture wearers, the distances from the medial line to the center of the occlusal load were statistically greater in the adjustment needed cases than in the control group. 3. In a case of periodontitis, the full arch fixed splint was adjusted using this system. After adjustment, the maximum occlusal force and contact area increased, and the maximum and medial pressure of the occlusal contact force decreased. 4. It was suggested that this system would be available for the examination of masticatory efficiency and diagnosis of various types of occlusions.

Tooth- and implant-supported prostheses: a retrospective clinical follow-up up to 8 years.

PURPOSE: The purpose of this study was to evaluate clinical treatment outcome of fixed prostheses in different sizes and with combinations of different numbers of teeth and implants as abutments. MATERIALS AND METHODS: A total of 115 implants were placed in 36 patients, 75 (65%) in the maxilla and 40 (35%) in the mandible. The implants were connected to 85 abutment teeth, 50 in the maxilla and 35 in the mandible. Of the prosthetic restorations, 19 were gold ceramic, 17 were gold acrylic, three were titanium acrylic, one was titanium ceramic, and one was titanium composite. The observation period ranged from 14 months to 8.9 years. The treatments comprised both fixed partial dentures supported by one tooth and one implant as well as complete-arch fixed prostheses supported by a number of teeth and implants. RESULTS: A total of nine implants were lost, three during healing and six after loading. The postloading cumulative implant survival rate was 89.8% after 5 years. Five abutment teeth were lost, and of the 41 prostheses included in the study, only two (5%) were lost during the observation period. Marginal bone loss was registered around 46 implants at the 1-year follow-up examination. During the following observation period, only slight changes in the marginal bone level adjacent to the implants and teeth were registered. The magnitude of technical complications was low. CONCLUSION: This investigation confirms the findings in similar studies that treatments with periodontally healthy teeth and implants splinted together in rigid one-piece superstructures show excellent long-term follow-up results.

A retrospective 5-year study of dental treatment in a group of elderly persons.

In a retrospective study, 50 patients over 70 years of age, selected from a private specialist clinic for fixed and removable prosthodontics, were studied. They all had remaining natural teeth and had undergone complete dental treatment at least 5 years before. The age-range was 70-96 and they had been treated 6-25 years before the study. The patients had on average 13.9 teeth. During the five-year observation period, 32 patients developed caries, with a mean number of 5.0 lesions (range 1-22). 79 fillings were made due to other defects than caries. 25 root canal fillings were made, due to caries lesions after loosened fillings or crowns in 5 cases and for other reasons than caries in 20 cases. 4.4% of the natural teeth had to be extracted. 19 crowns, 11 bridges and 1 splint were made. The prophylactic periodontal and cariological care delivered during the 5 years varied from 0 to 350 minutes (mean 89). The time for prophylactic treatment was not significantly correlated to the total number of natural teeth per patient but instead to the number of periodontally severely involved teeth (i.e. with 50% or less marginal bone support). The overall conclusion is that 3.5 times as much chairside treatment time was used for therapeutic measures as for prophylaxis.

Rationale for stabilization.

1. The subjective separation of the normal and the diseased periodontium for splinting purposes is artificial. With the exception of cases of secondary trauma from occlusion, the diseased periodontium should be treated in the same manner as the normal periodontium with regards to splinting. 2. Retionales for stabilization found to be valid are: I. Prevention of mobility A. Post acute trauma. B. In occlusal therapy. II. Prevention of drifting A. Replacement of missing teeth. B. Postorthodontics. III. In treatment of secondary trauma for occlusion. A. For functional stability. B. With unknown effects on the progression of periodontitis. 3. The relationship of trauma from occlusion and periodontitis is unclear at this time. 4. A need exists for a clinical test correlating histologic signs of trauma from occlusion and clinical findings. 5. Temporary splinting generally is not indicated during the initial or surgical phase of treatment of the periodontal patient, because mobility short of secondary trauma from occlusion does not impair healing.

Alterations on crown contour--effect on gingival health in man.

The effect of different supragingival crown contour on the surrounding marginal gingiva was studied on four patients. All the subjects had caries, esthetic problems, and minimal periodontal problems. Each patient received two splints; one side was overcontoured, and the other side undercontoured. The splints were observed at regular intervals within a 4-month period. The result of this study suggested that factors other than variation in supragingival crown contour in the range of +/- 1 mm determined gingival response within the first 4 months in patients with a predominately healthy periodontal structure.

[Studies on oral hygiene and periodontal prophylaxis in patients with jaw fractures].

Oral hygiene experiments with H2O2 and chlorhexidine rinsing were performed in 15 patients with dental splints for jaw fractures and intermaxillary wiring. To measure the various cleaning measures, Löe's plaque index (1967) was determined at the 7th, 21st, and 35th postoperative days. The 2% chlorhexidine gluconate was always by far superior to H2O2 as far as plaque inhibition was concerned. With chlorhexidine plaque reduction up to 69% and H202 reductions up to 22% were observed. After a test period of about 5 weeks, only slight side-effects were recorded, such as discolorations at the lingual side of the teeth and in few cases bad taste or dark coating of the tongue.

Salvaging terminal dentitions with convertible periodontal prostheses.

An alternative to the complete denture, the transitional prosthesis, the overdenture, and some tooth-splinting clasped partial dentures has been presented. The convertible periodontal prosthesis has many of the advantages of the overdenture, but few of the disadvantages such as palatal coverage, the appearance of a denture, and the psychologic effect. Preliminary observations over a 7-year period indicate that the periodontal condition of the abutment teeth improves. A case for periodontal worthiness of this method of periodontal prosthesis can be made.

Treatment of luxation traumatic injuries: definition and classification in the literature.

Luxation traumatic injuries affect the hard tissues and may involve periodontal tissues in severe cases. Periodontal healing must be considered during treatment of traumatic injuries that result in total luxation of the teeth. Pulpal healing is essential for the endodontic prognosis of a reimplanted tooth, as well as for its periodontal healing. Luxation injuries can be further classified as intrusive, extrusive, and/or lateral; this categorization further facilitates the mode of splinting and repositioning utilized during treatment. This article reviews various types of dentoalveolar traumatic injuries and discusses commonly incorporated treatment modalities.

Intraoral acrylic splints for maxillofacial fracture repair.

Maxillofacial fractures in dogs and cats occur secondary to vehicular trauma, falls, kicks, gunshots, and fights with other animals. Pathologic mandibular fracture may occur secondary to periodontal disease, neoplasia, and metabolic diseases. The primary objective for repair of maxillofacial fractures in small animals is return to normal function. Therefore, it is necessary to maintain occlusal alignment while providing adequate stability for bony union. Basic principles of maxillofacial fracture repair include anatomic reduction and restoration of occlusion, application of a stable fixation to neutralize negative forces on the fracture, gentle handling of soft tissues, avoidance of iatrogenic dental trauma, extraction of diseased teeth within the fracture line, and minimizing excessive soft tissue elevation. This review article will describe the application of intraoral acrylic splints for maxillofacial fracture repair.
