Primary Outcome Measures

Name	Time	Method
To evaluate the success rates of single wide-diameter implants placed at different times following extraction of molar teeth. <br>The success criteria of Zarb and Albrektsson (1998) and prosthodontic success criteria of Walton (1998) will be used.[After implant placement and then annually for up to 5 years]

Secondary Outcome Measures

Name	Time	Method
To evaluate the crestal bone level using standardised radiographs (Payne et al 1999) and peri-implant microbiota through collecting plaque samples for detection and quantification of microbial pathogens by real-time polymerase chain reaction (PCR)[After implant placement and then annually for up to 5 years]
