Brief summary

Research question The aim of this clinical trial is to assess the effectiveness of narrow diameter dental implant for replacing single missing back tooth. The narrow diameter dental implant will be compared to standard diameter dental implant in different aspects particularly the need for additional bone graft when placing dental implants. Background Dental implants can be used to replace missing teeth. However, the bone of the jaw shrinks in width and depth after tooth removal. Such bone loss may not allow the placement of dental implant with standard diameter and therefore bone substitute materials covered with artificial membrane are used along with dental implant placement. It is hoped that the use of dental implant with narrow diameter may allow implant placement in jaw bone that lost its width and hence provide a treatment modality that could be more comfortable and cost effective for the patient by avoiding the use of bone substitute materials and artificial membranes required for placement of dental implants with standard diameter. Methods It is anticipated to include 34 participants aged 18 years or older with a single missing back tooth. Several parameters will be recorded throughout the study to explore the advantages and limitations of using either implant size.

Interventions

Placement of 17 narrow-3.3 mm diameter TiZr single implants to replace single missing posterior tooth by periodontist. It is expected that contour augmentation is not required.
