Maxillary Immediate Loading with Fixed Implant-Supported Restoration in an Edentulous Patient: A Case Report
Dental News Volume XXII, Number II, June, 2015 by Dr. Rola Mortada, Dr. Mohammad Al Bazzal, Dr. Ibrahim Mortada, Dr. Khaldoun Rifai Introduction The original Bränemark protocol dictated that the initial phase of implant osseointegration should be at least 4-6 months before any prosthetic restoration is placed. 1 However, technological advancements have resulted in modern dental implant protocols that provide the possibility to immediately load implants. 2 Certain guidelines must be respected to reduce stress at the developing bone-to-implant interface and achieve osseointegration. Implants require primary stability of at least 45 Ncm insertion torque. Excessive micromotions exceeding 150 µm will prevent new bone formation and a noncalcified, collagenous poorly vascularized scar tissue will characterize the interface. 3 There is an assumption that joining several implants together via a rigid construction will reduce micromotion then facilitate the healing pro...
