Five-year survey of treatment with removable partial dentures. Part I.

A survey involving 137 patients treated with 203 removable partial dentures was conducted in England, the Netherlands, and the United States from samples of 1-year and 5-year posttreatment data. The objectives were to (1) develop a practical clinical and radiologic method to evaluate the results of removable partial denture treatment and (2) establish baseline values and results of removable partial denture treatment for use by all investigators. The results indicated the following: 1. Gingival pocket depth around abutment teeth was reduced at posttreatment examination. 2. There was an increase in posttreatment abutment teeth mobility that was greater in mandibular than maxillary teeth. Mobility increase was less for abutment teeth than for control teeth. 3. There was a slight loss of bone around abutment teeth that was about equal to loss around control teeth. 4. Oral care (plaque index) showed that 62.4% of all tooth surfaces had plaque accumulation at posttreatment examination. 5. Eleven of 616 abutment teeth (1.78%) were extracted.

Interdental wiring in jaw fractures: effects on teeth and surrounding tissues after a one-year follow-up.

Several authors have suggested that interdental wiring may have an adverse effect on the teeth and surrounding tissues. In the present study we examined 250 teeth that had been subjected to wiring and 142 adjacent teeth that had not been wired (controls). During the wiring period, and after a minimum of 1 year following treatment of the jaw fracture, the teeth and periodontal tissues were examined by periodontal probing, percussion sound test, mobility test, sensitivity test, and radiography. One tooth showed temporary increased mobility. Periodontal health was clinically and radiologically fully restored after a year in all teeth. Progressive caries was seen in 2 patients and was treated. Loss of sensitivity was seen in 3 teeth adjacent to the fracture site and in one tooth adjacent to a titanium cortical screw. However, these pulpal changes either recovered spontaneously or were treated endodontically. There were few late problems in the teeth and surrounding tissues. In 243 teeth (97%), completely healthy conditions were found in pulp and periodontium. There was no evidence of root resorption or dentoalveolar ankylosis. We conclude that late deleterious effects on the teeth and periodontal tissues from interdental wiring in the treatment of jaw fractures were uncommon 1 year after the removal of the interdental wiring.

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.

In vitro study of cementation of cast splints on nonmobile and mobile teeth.

The marginal opening of a fixed splint on movable and firm abutments was investigated. Regular-body poly(vinyl siloxane) was used as a luting material to cement a three-unit, cast complete crown splint on three metal dies in an acrylic resin model. The middle abutment was set first in acrylic resin and subsequently in a displaceable material. The cement replica was recovered, measured, and compared. The mean cement thickness for the mobile displaceable abutment was significantly greater (P less than 0.001) than that of nonmobile teeth.

Gingivitis induced by gingival impaction in monkeys.

Impaction of the gingival sulcus with elastic bands deforms the gingival sulcus, forming a surface for growth of bacterial plaque, compresses and causes necrosis of surface epithelium and the subjacent lamina propria. The teeth become extruded and make premature contact with their apposing teeth. During mastication, forces applied to extruded teeth probably contribute to their displacement, resulting in their mobility. An inflammatory process commences within 3 days and becomes clinically evident by 7 days. The gingival becomes red-magenta in color and is slightly hemorrhagic. Pockets 4 to 6 min. in depth form within 1 week and remain as long as the impacted substance occupies the space between the tooth and the sulcus epithelium. Removal of the impacted substance results in prompt repair, with complete restoration within 3 weeks. Such repair may be by an epithelial attachment rather than by a fibrous periodontal ligament.

[Effect of occlusal therapy with FRC splint on periodontal parameters in maintenance phase].

The purpose of this study was to evaluate the changes of the periodontal parameters of mobile, but splinted teeth with intracoronal fiber reinforced composite and compare to non-mobile teeth in maintenance phase. We splinted 73 teeth (29 non-mobile, 44 mobile) in 18 cases. The periodontal parameters - probing depth, gingival index (Loe-Silness, 1964), plaque index (Silness-Loe, 1965) - were monitored clinically immediately, 1 year and 2 years after complete periodontal treatment. There were scored 69 treated teeth after 1 year and 37 treated teeth after 2 years. Statistical comparisons were performed using Wilcoxon test for two related parameters and Mann-Whitney U test for two independent parameters in the software package SPSS 11.0 for Windows (SPSS, Chicago, IL, USA). There was not mobility recorded at splinted teeth neither after treatment immediately nor at recall visits. The periodontal parameters demonstrated no significant changes of probing depth (-0,08 +/- 0,41, 0,05 +/- 0,51) and gingival index (-0,32 +/- 0,79, -0,32 +/- 0,75) 1 and 2 years after complete therapy. There was significant decrease in plaque index (-0,77 +/- 0,43, -0,36 +/- 0,55) measured at recall visits. No significant differences were detected between the mobile and the non-mobile groups in all parameters. No significant correlation between changes of gingival index and plaque index was determined. The intracoronal FRC splint do not obstruct the individual and professional oral hygiene. The stabilize of mobile teeth allow the same healing like a non-mobile teeth.

[A new technique for the treatment of ectopically erupting permanent first molars].

The problem and treatment of the ectopically erupting permanent first molars have been addressed by many authors since they were first mentioned in the literature by Chapman in 1923. Many treatments involve techniques using the primary second molar. It is better for correcting the eruption of the permanent first molar into normal occlusion to maintain the primary second molar in its normal position. However severe mobility and root resorption are often present when an ectopic eruption is found. An 8-year-old male with ectopic eruption of the maxillary right permanent first molar was examined and treated. The right primary second molar demonstrated severe mobility and root resorption, and therefore a new appliance using the primary first molar was designed. After 4 months from the beginning of the treatment the mobility of the primary second molar decreased, and after 6 months the permanent first molar almost erupted in its normal position.

Splinting of teeth with fixed bridges: biological effect.

Forty abutment teeth with pathological mobility were splinted with telescoped removable bridges. During the first 4 weeks the bridges were fixed. From the beginning of the fifth week they were removed once a day. Mobility was measured prior to placing the bridges and at 4 and 10 weeks intervals. Average mobility of the abutment teeth and the control unsplinted teeth did not change significantly during the experimental period.

A new reinforced intracoronal composite resin splint. Clinical results after 1 year.

An intracoronal technique for semipermanent splinting of mobile or migrating teeth is described and clinically evaluated. Circumferential grooves of 1 to 1.5 mm depth were cut into the enamel in the occlusal third of the teeth to be splinted. The teeth were splinted by placing a polyester ligature in two or more figure-8 loops along the grooves, and sealing the grooves and interproximal contact areas with an acid-etch composite resin system. A total of 51 splints involving 183 teeth and 132 interproximal contact areas were placed in 34 patients. One year after insertion, 46 splints were found intact. Five splints presented with one fractured interdental element, each. Average mobility of the splinted teeth was 51% below the preoperative level. Splinting improved the masticatory comfort. The esthetic results were satisfactory.

In vitro consistency of the Periotest instrument.

PURPOSE: The consistency of measuring the damping characteristics using the Periotest (Siemens AG, Bensheim, Germany) was studied. MATERIALS AND METHODS: Periotest values (PTV) of three rods embedded in various depths of impression material were recorded by seven dentists. RESULTS: There is no statistically significant difference among the subjects in measuring PTV of any of the three rods. However, the variation in the occlusal-gingival position of impact resulted in statistically significant different PTV measurements of each of the three rods. Assessment of mobility of the same objects using a clinical criterion was found to be less consistent as the mobility of the object increased. CONCLUSION: In vitro PTV measurements are consistent provided that the position of impact is controlled.

[Effect of wire ligature splint reinforced with preparing groove and employing composite materials on the teeth with severe periodontitis].

Teeth with severe periodontitis exhibit alveolar bone loss, teeth mobility and even teeth loss. The author made groove along the buccal and labial surfaces of teeth, twisted the stainless steel wire and placed ultraviolet light polymerized composite resin over the wire. Teeth with mobility 2-3 degree from 39 patients were treated and the effect was evaluated in the period of 2 to 4 years. The results demonstrated that the treatment had advantages of stabiliting very loose teeth and forming a firm unit. It minimized teeth mobility and improved greatly teeth occlusal function. When occlusing, the device could redirect force to other teeth, thereby reduced traumatism and facilitated periodontal tissue repairing and regeneration and protected loose teeth.
