Patient's Satisfaction of Mandibular Implant Supported Overdentures With Reduced Denture Base Extensions.

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.
