Gingival recession and tooth mobility.

Tooth mobility measurements were carried out on 107 teeth with gingival recession in 20 subjects. Alveolar bone dehiscence around 43 of these teeth was measured during flap surgery in 13 subjects. No significant correlation was found between gingival recession and tooth mobility, and between tooth mobility and alveolar bone dehiscence. A positive, significant correlation was present between gingival recession and bone dehiscence. In 17 of the subjects, tooth mobility of 29 homologous contralateral teeth with and without gingival recession was compared. The difference was not significant. The role of trauma from occlusion in the etiology of gingival recession is questioned.

The use of laser beams for measuring tooth mobility and tooth movements.

The laser reflexion method, a direct contactless measuring technique with a high accuracy, has been applied for clinical purposes. A prototype has been tested using a laser beam to illuminate a patient's tooth fixed to the equipment by an impression plate. The reflected patterns were thrown onto a screen with a coordinate system and photographically recorded, and the movement of the tooth has been geometrically calculated. The relapse tendency after orthodontic treatment of a patient with periodontal disease and parafunctions was studied by repeated measurements of the left medial upper incisor. By use of the method, it was possible to observe that the velocity of the studied tooth was highest during the 1st day and, besides the horizontal movement, a rotation of the tooth began at the end of the measuring period.

[Value and significance of tooth mobility measurements].

1. The measurement of tooth mobility by manual and instrumental techniques is necessary for establishing a diagnosis, since it is of considerable importance for decisions in the framework of prophylaxis and therapy. 2. The significance of the measurement of tooth mobility depends upon the respective problem and the sensitivity of the measuring technique used. 3. The specifications for the precision of the measuring technique will be determined by the specific objective of the examination. 4. The instrumental measuring techniques are reproducible and, therefore, imperative in scientific studies.

An evaluation of clinical tooth mobility measurements.

This study evaluated the reliability and reproducibility of the modified Miller Index of horizontal tooth mobility. Each of three periodontists utilizing the modified Miller Index assessed the horizontal tooth mobility of 50 teeth in five subjects. The same teeth were also evaluated by the periodontometer. The results of these two methods were then compared. It was found that: (1) there were a high positive correlation between the periodontists' (pooled) assessment of clinical tooth mobility and the measurements of the periodontometer, (2) in any given patient the three periodontists (pooled) were highly accurate in their ability to rank teeth in order of their mobility as determined by the periodontometer, and (3) the periodontists (individually) were not as consistent when comparing teeth with the Miller Index across different subjects. The periodontists did not accurately utilize the Miller Index as it was originally described. It appears that the periodontists either ignored the reference to 1 mm in the description of the Miller Index, or they were unable to estimate what constitutes 1 mm of movemnet in the mouth. The periodontists all consistently scored as a 2 degrees mobility a tooth that moved approximately 0.5 mm not 1.0 mm as described by Miller. It is suggested that the modified Miller Index as described here provides an efficacious system for evaluating horizontal tooth mobility. It provides accurate, reproducible mobility scores in clinical studies requiring an estimation of this parameter. However, for individual teeth, when the clinician or researcher is trying to evaluate the effects of therapy on the periodontium and relatively few evaluation are made, the modified Miller Index may not provide the required degree of sensitively.

The effect of splinting on tooth mobility. (2) After osseous surgery.

The purpose of this study was to determine if fixed splinting of teeth with intraoral wire and acrylic splints had advantages with respect to tooth mobility, bone level and attachment level over unsplinted teeth following osseous surgery. Ten patients were chosen who exhibited bilaterally similar chronic destructive periodontitis and mobile teeth. One maxillary sextant was splinted, while the other was unsplinted. Both sextants functioned against an unsplinted mandibular arch. Following initial therapy, osseous surgery was performed in both maxillary sextants on the same day. Tooth mobility data was collected 1 week before and at 3, 6, 12, and 24 weeks following surgery. Levels of gingival attachment and bone were recorded before and 24 weeks after surgery. Splints were removed before measurements, then replaced, and the occlusion refined. Prophylaxes and oral hygiene instruction were repeated every 3 weeks throughout the study. For all categories of teeth and mobility examined, tooth mobility increased initially after surgery and subsequently decreased by 24 weeks to about presurgical values. The splinted and unsplinted segments reacted similarly throughout the study; splinting did not significantly reduce the mobility of individual teeth. Pre- and postsurgical bone and gingival attachment levels were also similar for the splinted and unsplinted segments.

Selection of retainers in lower overlay denture-in relation to the abutment tooth mobility--(a laboratory study).

This study was done to evaluate the art of retaining the lower sub/complete, overlay denture, in relation to the abutment tooth mobility while the force was applied to the denture. The lower overlay denture was placed on a simulated model which was constructed of methylmethacrylate and silicone rubber. The author developed and used the special devices for measuring the tooth mobility. Results obtained were as follows: 1. When a force is applied directly to the abutment, the tooth mobility, i.e. the lateral excursion of the tooth, is markedly reduced according to the favorable ratio of the clinical crown to the root length. Splinting by the bar is effective to reduce the lateral excursion. 2. When a force is applied to the denture indirectly to the abutment tooth, the lateral excursion changes greatly according to the retainer selected. 3. The clasp retainer shows the greatest change in the lateral excursion against every loading on the denture. 4. All three types of bar attachment show the least value of lateral excursion.

The effect of splinting on tooth mobility. I. During initial therapy.

The purpose of this study was to assess whether fixed splinting aided in the reduction of posterior tooth mobility during initial therapy. A "split-mouth" approach was used in order to compare splinted segments with similar unsplinted segments. Seven patients were selected, all of whom demonstrated chronic destructive periodontitis and mobile teeth. Initial therapy, consisting of oral hygiene instruction, root curettage and occlusal adjustment, was performed over a 2-week period. At the time of initial therapy, teeth in contralateral segments were splinted with an intracoronal wire-and-acrylic splint. Tooth mobility and gingival inflammation were recorded in all four segments every 3 weeks for a 15-week monitoring period following initial therapy. The splints were removed before each data recording session and then replaced and the occlusion refined. Prophylaxis and oral hygiene instruction were repeated every second week throughout the monitoring period. The reduction in the mobility of teeth splinted during the entire therapy period did not differ from the reduction observed in the unsplinted segments. The reduction in tooth mobility observed in both the splinted and unsplinted segments over the 17-week period can be attributed to the improved occlusal relationships and reduction in inflammation.

[Tooth mobility in several age groups with reference to various periodontal diagnostic aspects].

The present study deals with a study of the tooth mobility, the pocket depth and the bone destruction in 616 periodontally healthy subjects. It was found that the mobility of the upper lateral incisor is inferior to that of the central one. Furthermore, relations of age to tooth mobility and bone destruction were established, whereas no relationship between age and pocket depth was evident.

Familial ogee roots, tooth mobility, oligodontia, and microdontia.

The term ogee is proposed to describe dome or onion-shaped incisor roots as presented in a family study. A case of ogee permanent upper incisor teeth associated with microdontia, oligodontia, and tooth mobility is described. Forty-seven members of the proband's family were examined. The dental abnormalities were found to be of an autosomal dominant pattern of inheritance.

The use of removable partial denture splints in the treatment of postsurgical tooth mobility.

The theory and clinical use of removable partial denture splints has been offered as a tenable solution to the problem of postsurgical tooth mobility. The close cooperation of the periodontic and prosthetic specialties is in many cases vital to the ultimate success of treatment and longevity of the dentition. Although not presented as a panacea, it is hoped that clinicians will bear this clinical entity in mind as an option in the treatment of periodontally debilitated dentitions.

[Studies with the HSE-digital periodontometer on tooth mobility and for checking of clinical degrees of mobility].

The mobility of normal teeth and teeth with periodontal lesions could be measured by means of the newly constructed HSE-digital-periodontometer and specially developed measuring head. After obtaining norm values, measurements of pethological changes allowed us to determine to what degree the clinically increased mobility of teeth was subject to subjective influences (range of error 36.5 to 70.5%). These results suggest that the scale of clinical grades of tooth mobility be increased to 5 altogether and that practical objective measuring apparatus be developed especially for dental practice.

Occlusal characteristics and tooth mobility in periodontally healthy young males classified orthodontically.

Three groups of periodontally healthy young males classified as to orthodontic status by the Handicapping Labio-Lingual Deviations Index were evaluated for various occlusal characteristics. A much larger proportion (95%) of the orthodontically normal subjects (Group I) had an Angle Class I type of occlusion than the Group II subjects requiring orthodontic care (60.5%), or the Group III subjects who had received orthodontic care (63.4%). The percentages of subjects with a "cuspid-protected" type of occlusion were larger in the orthodontically normal and orthodontically treated groups than in the group requiring orthodontic care. Anterior displacement of the mandible in closing from centric relation to the intercuspal position was found in the majority of subjects in each group. Displacement of more than 2 mm was most common in the subjects requiring orthodontic care. Only 1 of the 41 orthodontically treated subjects reported that his occlusion had been adjusted by grinding after tooth movement. There were no statistically significant differences in mean tooth mobility values between the orthodontically normal and orthodontically treated subjects. The lateral incisor tooth had a significantly lower mean mobility value in subjects whose orthodontic care included removal of the first premolar than in subjects treated without removal of the first premolar. Wear facets were common in all three groups. Based on the findings, one can conclude that orthodontic therapy was only partially successful in obtaining the objectives described as part of an ideal result. It should be noted, however, that the status of the dentition and occlusion prior to orthodontic treatment could not be determined for more than a few subjects.
