An evaluation of the effects of two distal extension removable partial denture designs on tooth stabilization and periodontal health

Abstract

A 30-month follow-up study was conducted on 36 patients to evaluate the effects of the lingual plate as a major connector in distally extended removable partial dentures (RPDs) on tooth stabilization. At the same time, the study evaluated the effects of lingual plate-type RPDs and lingual bar-type RPDs on periodontal health. The most striking finding of the study was that, with the exception of gingival recession (GR), periodontal conditions improved with both types of RPDs. At the end of 30 months, there were significant differences in plaque index, GR and tooth mobility (TM) values between treatment groups (P < 0.05). Plaque accumulation was greater in the lingual plate treatment group; however, this did not result in periodontal breakdown. There were no statistically significant differences between treatment groups with respect to pocket depth, gingival index or attachment loss (P > 0.05). Moreover, patients treated with lingual plate-type RPDs demonstrated less TM when compared with patients treated with lingual bar-type RPDs at the end of 30 months follow-up. Overall study findings established that with adequate checks on oral and denture hygiene at regular intervals, patients with RPDs may even experience improved periodontal health. Moreover, the clinical interpretation of decreased TM observed in patients treated with lingual plate-type RPDs may be questionable as the plaque accumulation was greater in the lingual plate treatment group inspite of periodic recalls.

Rehabilitación de maxilares clases I y II de Kennedy mediante prótesis removibles

“…La eventual excesiva rigidez de este complejo retentivo, debe a nuestro entender soslayarse, puesto que se está en presencia de un caso "límite" en cuanto a los recursos de que disponemos para que la prótesis tenga una mínima retención funcional y además, porque sabemos empíricamente que la mayor o más relevante agresión que puede resultar biomecanicamente perjudicial para un diente, proviene de la periodontitis y su potencial resultado de reabsorción ósea alveolar (14,15) . También hemos generado otra modificación, eliminando la plataforma disto proximal del diseño original.…”

Removable Partial Denture Designing: Variation of Hard and Soft Tissue Anatomy and Maxillary Major Connector Selection

“…Periodic checkup and oral hygiene measures of RPDs' users are essential to improve periodontal health and prosthesis longevity [17]. In contrary, Cosme et al, reported that there is no relation between oral hygiene and prosthesis [5,18].…”

“…In a study done by Janaina et al, it was concluded that RPDs en-OPEN ACCESS http://scidoc.org/IJDOS.php hanced tooth mobility, diminished prevalence of caries and did not induce the fractures of abutments [62]. For RPDs longevity and improve periodontal health in RPDs' users, satisfactory and regular oral hygiene conditions checkups were required [17].…”

Adjunctive Intracoronal Splint in Periodontal Treatment: Report of Two Cases

“…1 Penelitian klinis menunjukkan bahwa penyembuhan setelah perawatan penyakit periodontal berupa pembentukan dan maturasi jaringan lebih baik pada gigi yang tidak mengalami kegoyangan dibandingkan dengan gigi yang goyang. 2 Gigi goyang cenderung memiliki prognosis yang lebih buruk dan respon yang kurang baik terhadap terapi periodontal. 3 Splinting diharapkan dapat membantu peningkatan perlekatan jaringan periodontal pada kasus-kasus periodontitis.…”
