Oral yeasts, mucosal health, and drug use in an elderly denture-wearing population.

Drug use among the elderly may be a factor in oral mucosal pathology and the prevalence of oral yeasts. This study was designed to evaluate the relationship between oral yeast, denture-bearing mucosal health and drug use, especially drugs with known hyposalivatory side effects. There was an inverse relationship between denture-bearing mucosal health, and hyposalivatory drug use r = -0.41 P less than 0.04. Use of drugs with a hyposalivatory side effect was related to increased numbers of Candida glabrata but not Candida albicans in saliva and at denture stomatitis and denture sore sites.

Overdentures for acquired and congenital anomalies: 1. Complete dentures.

Overdenture principles can be applied to dentitions that are relatively complete without preparation or alteration of the existing teeth. Such overdentures may cover the traditional denture-bearing tissues as well as the unaltered remaining teeth. The primary advantages derived are reversibility, simplicity, and cost effectiveness. The primary indications are restoration of congenital and acquired anomalies. A detailed clinical and laboratory technique for fabricating these overdentures is presented. Effective restorations require care and attention to detail using the principles of conventional prosthodontics. No special equipment or material is needed. Two patient histories are presented, illustrating use of the technique.

Overdentures for acquired and congenital anomalies: 2. Partial overdentures.

The use of complete overdentures for the restoration of acquired and congenital anomalies has been advocated for many years. This therapeutic approach can provide an esthetic and functional restoration for missing, malformed, or discolored dentition. For some patients, tissue coverage similar to a complete denture is disconcerting, especially when the majority of the teeth are present. The removable partial overdenture provides a functional, esthetic, and economical alternative. A technique is described for the fabrication of the partial overdenture for acquired and congenital anomalies.

Immediate implantation of pure titanium implants into extraction sockets of Macaca fascicularis. Part I: Clinical and radiographic assessment.

Immediate implants have the advantages of few surgical exposures, short treatment time, and maintenance of alveolar bone height and width. The purpose of this study was to compare immediate implants with conventional implants (implants placed into ossified extraction sites) in adult monkeys. Forty-eight implants were placed and allowed to heal for a 6-month period. Following a 7-month loading period, the monkeys were sacrificed, and implant sections were evaluated histologically. Clinical and radiographic measurements showed few significant differences between immediate and control implants.

Immediate implantation of pure titanium implants into extraction sockets of Macaca fascicularis. Part II: Histologic observations.

The purpose of this study was to evaluate immediate implants with implants placed in ossified extraction (control) sites. Histologic observation of immediate and control implants showed similar levels of bone integration at the light microscopic level using ground-section and decalcified thin-section histologic methods. Both histologic methods provided similar information in relation to determination of hard and soft tissue components measured at the interface. The percentage of bone integration was similar in different anatomic regions of the oral cavity. Bone patterns peripheral to the interface region differed, suggesting that special consideration be given to implants placed in the posterior regions of the maxilla and mandible.
