Study Type: Interventional

Official Title: An Open, Prospective, Controlled Study in the Maxilla to Evaluate Clinical Outcome of ASTRA TECH Implant System, OsseoSpeed™ Implants in Single Tooth Replacement Using an Immediate Loading Proto

Brief Summary: The purpose of this study is to evaluate survival for ASTRA TECH Implant System, OsseoSpeed™ implants following immediate loading in extraction sockets versus immediate loading in healed ridges. Patients in need of single standing implants replacing teeth in the maxilla within zone 15-25 will be included and followed for 5 years. Primary objective is implant survival rate at 12 months.

Sponsor: Dentsply Sirona Implants

Current Primary Outcome: Implant Survival [ Time Frame: 12 months after implant placement ]

An implant that has failed to osseointegrate, lost its osseointegration or fractured was considered a failure effective from the date of removal. The survival rate for individual implants was analyzed at each visit. Cumulative implant survival rate was calculated using Kaplan-Meier life-table estimation and reported as percentage of survived implants.


Original Primary Outcome: Implant Survival [ Time Frame: During 12 months after implant placement ]
