The effect of acrylic removable partial dentures on periodontal health of abutment and non-abutment teeth

Abstract EN

Background : Acrylic removable partial denture (ARPD) is a common treatment available for restoration of partially edentulous ridges.

Longitudinal studies ind icate that ARPDs have been associated with increased gingivit is, periodontitis and abutment mobility.

The aim of the present study is to compare the effect of ARPDs on periodontal health of abutment and non-abutment teeth.

Material and method : A total of 30 patients prepared to wear ARPDs participated in this study they were 14 males and 16 females aged 35 to 50 years.

Plaque and gingival indices as well as bleeding on probing and probing pocket depth were measured, both on abutment and non-abutment teeth immediately before placement of the partial dentures then 6 and 12 months after placement of the partial dentures.

Results : Significant differences were noticed on plaque and gingival ind ices plaque index was 1.8 and 0.9 for abutment and non -abutment respectively while gingival index was 1.8 and 0.8 at the end o! the study The percentage of the surfaces of abutment teeth with bleeding on probing was 32% and only 12% for nonabutment teeth at the end of the stud) .Only 3% of the surfaces of non-abutment teeth denotes a pocket depth of > 4mm and 14% for abutments at the end of the study .

Non significant differences were found on bleeding on probing and probing pocket depth between abutment and non-abutment teeth.

Conclusion : ARPDs can produce a lot of adverse effect on periodontal tissues due to the presence of foreign body in the mouth and it's suppression to the natural cleansing mechanism.

The patients most be instructed in appropriate techniques of oral hygiene.

ARPDs may be indicated as in term or transitional prosthesis for a period not exceed 6 months.
