Summary

This study aimed to compare reduced (partially extended) denture bases with fully extended bases regarding patient satisfaction, oral health-related quality of life (OHRQoL), and masticatory efficiency.

A within-subject study design was carried out; involving 20 completely edentulous participants aged 50-75 years, who received newly constructed conventional complete denture. Four parallel implants were installed in the interforaminal region, implant overdenture (IOD) retained by bar attachment was constructed for each patient and were provided with two different overdenture designs: (1)firstly a fully extended denture base (FIOD) (2) then a reduced (partially extended) denture base (RIOD). Each patient allowed to wear each types of overdentures for a period of 3 months prior to evaluation. The following outcome measures were assessed: Patient satisfaction, the Oral Health Impact Profile (OHIP-14), and Chewing efficiency were assessed.

Interventions

PROCEDURE

Four parallel implants were installed in the interforaminal region

All participants administrated prophylactic antibiotics one day before implant placement and continued 7 days after surgery. Participants were asked to rinse their mouth with chlorhexidine mouthwash just before surgery and 7 days after surgery. Under local anesthesia, four implants were placed bilaterally in the interforaminal region. Four parallel implants (TioLogic, Dentaurum) were inserted in the inter-foraminal area using the submerged surgical approach and delayed loading protocol. By using the stereolithographic surgical guide the Implants were installed by the same surgeon with a minimum torque of 35 Ncm to give high initial stability. Relief was done in the mandibular denture over the implants and tissue conditioner (Visco-gel; DENTSPLY, Weybridge, UK) was used as a relining material. osseointegration was allowed to occur for a period of 3-6 months prior to final restoration.
