This document summarizes a course on periodontology and implantology taking place from January 23-26, 2015. It discusses the history of dental implants beginning with Branemark's pioneering research in 1952 which showed that titanium screws could successfully integrate with bone tissue over time. The document contrasts conventional delayed loading of implants with immediate loading approaches and notes factors like initial stability, bone quality and surface roughness that influence successful integration. It also reviews the biological considerations of the initial healing phase when an implant interfaces with living bone.
