Objectives: To compare the survival of immediate implants placed in postextraction infected and non-infected sites, restored with cemented crowns. Methods: Thirty-six implants were immediately placed in non-infected sockets (control group (CG), n = 18), and in infected alveoli (test group (TG), n = 18) that had been debrided, curetted, cleaned...

Objectives: The objective of this in vitro study was to evaluate the use of the Neodymium:Yttrium-Aluminium-Garnet (Nd:YAG) laser as part of the root canal treatment on the penetration of sealer into dentinal tubules. Methods: Eighty extracted lower premolars were randomly assigned to two groups (n = 40 each): Control group (CG), subjected to...

Objectives: To validate a new index for assessing the whole concept of oral health-related quality of life (OHRQoL) of implant-prosthesis wearers. Methods: 113 patients who were not requesting dental treatment were assigned to: Group 1 (CD; n = 38): complete denture users (control); Group 2 (IO; n = 38): implant overdenture wearers; and Group 3...

Barrier membranes are employed in guided bone regeneration (GBR) to facilitate bone in-growth. A bioactive and biomimetic Zn-doped membrane with the ability to participate in bone healing and regeneration is necessary. The aim of the present study is to state the effect of doping the membranes for GBR with zinc compounds in the improvement of...

Objectives: To evaluate the influence of bone type in terms of bone density and cortical bone thickness, on the stresses induced by two implants under compressive and oblique loads. Methods: A numerical simulation technique based on the finite element method was applied. Two implant types (M-12 and Astra Tech) were introduced in a model matrix...
