Abstract
Objectives:The aim of the study was to assess the knowledge and practice of implant retained restorations (IRR) among senior dental students in Saudi Arabia.Methods:Four hundred questionnaires were distributed among senior dental students of five dental schools in Saudi Arabia. Student’s knowledge was assessed regarding which implant restoration [cement retained restoration (CRR) or screw retained restoration (SRR)] better provides the desired clinical properties. Students’ practice of IRR, perception of their knowledge and need for further education related to IRR were also assessed. Descriptive statistics and chi-square test were employed to assess collected data.Results:Three hundred and fifty four senior dental students responded at a response rate of 88.5%. Thirty three percent respondents did not have any practical experience of IRR. Students showed a clear preference for CRR with regards to aesthetics (71.4%), passive fit (55.3%), fabrication ease (57.3%) and fracture resistance (40%). SRR were considered to provide better retention (59.6%), soft tissue health (51.1%) and ease of retrievability (72%). Nearly 40% of students agreed that they did not get sufficient information related to IRR in undergraduate courses.Conclusions:Clinical training of IRR is compromised in the undergraduate curriculum in dental schools of Saudi Arabia. The knowledge of dental students regarding IRR was broadly in line with current evidence.
Highlights
Excellent survival rates of dental implant restorations have lead to their extensive use in the rehabilitation of patients through the years.[1,2] Multiple factors influence the clinical success with dental implants, including oral hygiene, systemic patient health, patient habits, type of suprastructure (Cement or screw retained) and occlusal loads.[3,4,5] The choice of implant restoration type [cement retained restorations (CRR) or screw retained restorations (SRR)] is a critical decision and is influenced by factors like mechanical complication, esthetic outcomes, ease of maintenance and financial implications
This study presents data regarding practice and knowledge of dental implant restorations (SRR and CRR) among senior dental students of Saudi Arabia
Fifth year dental students and interns were included in the study, as they are taught courses related to implant dentistry in the final year of the dental curriculum and internship provides further clinical exposure aimed at training of implant-supported restorations of future general dental practitioners (GDP)
Summary
Excellent survival rates of dental implant restorations have lead to their extensive use in the rehabilitation of patients through the years.[1,2] Multiple factors influence the clinical success with dental implants, including oral hygiene, systemic patient health (such as diabetes and osteoporosis), patient habits (smoking), type of suprastructure (Cement or screw retained) and occlusal loads.[3,4,5] The choice of implant restoration type [cement retained restorations (CRR) or screw retained restorations (SRR)] is a critical decision and is influenced by factors like mechanical complication, esthetic outcomes, ease of maintenance and financial implications. A large number of implant complications are associated with IRR (such as, de-cementation, veneer fracture, screw loosening).[13,14]
