An evaluation of the long-term wear of a distal extension-removable partial denture on abutment teeth that have undergone periodontal therapy

Although the evidence is clear on long-term effects of removable partial dentures (RPDs) periodontal health abutment and non-abutment teeth, little work has been done outcomes remaining teeth previously treated with therapy. The aim this study was to evaluate effect denture loading exposed treatment additional photo-disinfection. Twelve partially edentulous patients classified as having mandibular Kennedy Class I arches were included. In each quadrant arch, terminal diagnosed have untreated chronic periodontitis. Initially, all affected abutments received a conservative in form scaling conventional root debridement. Patients randomly photodynamic therapy one quadrants (test group). After treatment, 4-week load-free period planned. Mandibular distal extension RPDs fabricated restore missing teeth. clinical parameters including plaque index (PI), gingival (GI), recession (GR), probing pocket depth (PD), attachment level (CAL) tooth mobility (TM) assessed at baseline, then for two 6-month recall appointments over twelve months after prosthetic treatment. addition, mean annual vertical bone loss also assessed. Except PI, GR, PD, values GI, CAL, TM scores test group significantly lower than those control group. Better results observed proximal sides suggest that RPD by periodontitis may perform better when both debridement antimicrobial
