Non-crown and bridge stabilization of severely mobile, periodontally involved teeth. A 25-year perspective.

It is the author's belief, after analyzing forces and stresses on the periodontium for more than 30 years, that stabilization of severely mobile teeth can retain teeth, if in health, almost indefinitely. Because these teeth are retained using restorative materials, recurrent caries is a problem that needs to be treated. Tooth loss resulting from caries can occur. In the author's 26 years of using extracoronal adhesive resins for splinting, the technology of adhesive bonding and restorative resins have been improved. Earlier shortcomings of the physical properties of these materials never dissuaded the author from recommending splinting. When the cases were presented to the patient and the referring dentist, the types of the current materials used to splint teeth were immaterial. Realizing that improvements in adhesives and resins would be developed, the near-hopeless teeth were retained. Because the elderly population is the fastest-growing segment of the population, caries control is more of a concern than it was 50 or more years ago. Because teeth are being retained longer in this cohort, and because caries has a greater potential to exist, supportive periodontal therapy and recalls and caries examination become more important.

Natal teeth: a review.

The incidence of natal teeth is approximately 1:2,000 to 1:3,000 live births. The most commonly affected teeth are the lower primary central incisors. Natal teeth usually occur in pairs. The eruption of more than two natal teeth is rare. The majority of natal teeth represent the early eruption of normal primary deciduous dentition. Less than 10% of natal teeth are supernumerary. Natal teeth might resemble normal primary dentition in size and shape; however, the teeth are often smaller, conical and yellowish, and have hypoplastic enamel and dentin with poor or absent root formation. Complications include discomfort during suckling, sublingual ulceration, laceration of the mother's breasts and aspiration of the teeth. A dental roentgenogram is indicated to differentiate the premature eruption of a primary tooth from a supernumerary tooth. Tooth extraction is indicated if the tooth is supernumerary or excessively mobile. If the tooth does not interfere with breastfeeding and is otherwise asymptomatic, no treatment is necessary.

[Biometric studies on implanted and natural abutments].

The mobility of 50 osseointegrated implants, inserted for improvement of the support of dentures in edentulous lower jaws, was studied during a period of up to 3 years by means of mechano-electronic measurements. The results showed that 3 months after implantation osseointegrated implants have less quasi-static mobility than natural teeth without periodontal lesions. Under the stresses of mastication the mobility of osseointegrated implants continuously increases. After 2-3 years, implants show a similar mobility as natural teeth supporting comparable denture constructions. The Periotest readings of implants were significantly lower than those of natural teeth, largely independent of the date of mobility measurement. A prognosis of functional properties as well as predicting the impending loss of osseointegrated implants is possible with the aid of long-term mobility measurements.

The bite plate--an adjunct in periodontic and orthodontic therapy.

This report reviews bite plate therapy and describes several variations of bite plates. Bite plates may be useful as an adjunct to periodontic and orthodontic therapy. They may be used as a diagnostic appliance, to take mobile teeth out of trauma by disarticulating them, to allow teeth to extrude and shallow out associated osseous deformities, and to eliminate the superimposed occlusal trauma that may be caused by the parafunctional habits that can develop during orthodontic tooth movement. The change in vertical position of the dentition and the decrease in overbite are primarily due to eruption of the posterior teeth and not intrusion of the lower anterior teeth. The decrease in overbite may be accompanied by an increase in overjet and an alteration of the mesio-distal and bucco-lingual occlusal landmarks. In some cases the use of a bite plate may cause the development of an anterior open bite. Any such occlussal alterations produced by the bite plate should be corrected by occlusal adjustment or orthodontic therapy and occlusal adjustment.

[Clinical trials of solcoseryl in the treatment of parodontium diseases].

The effect of Solcoseryl on the clinical state of the parodontium was assessed in 26 patients aged from 18 to 57 years with the diagnosis of deep parodontopathies. Each patient received 30 ampoules of 2 ml of Solcoseryl for one course of the treatment. Submucous injections of the drug near the teeth 13, 23, 33 and 43 were done as follows: during the first 10 days one ampoule daily, then 10 injections every other day, and 10 injections at three-day intervals. The condition of the parodontium was assessed before and after the treatment by means of the PI, GI, GBI and teeth mobility indices, and measurements of the depth of gingival pouches--K, and volume of fluid in pouches SFFR according to Brill. The therapeutic method applied in these cases had a good effect on reduction of gingivitis, bleeding and volume of secreted pouch fluid but had only a small effect on teeth mobility and depth of gingival pouches.
