Study Notes

The use of Enhanced Osteogenesis on SLA (Surface Layer Analysis) surfaces results in better osseointegration than conventional TPS (titanium plasma spray)
Less bone resorption was observed with Enhanced Osteogenesis after a 3-year follow-up compared to TPS
Biomechanics plays a crucial role in implant dentistry
Primary stability and insertion torque are important factors in implant dentistry, but they are not the same
Primary stability refers to the initial stability of an implant in the bone, while insertion torque is the maximum force applied during implant placement
Primary stability can be assessed through subjective assessment, maximum insertion torque, or resonance frequency analysis
Implant placement protocols include same-day placement, delayed placement, and various loading protocols
The placement protocol classifications include Type 1, Type II, Type III, and Type IV implants
The loading protocol classifications include immediate restoration or non-functional loading, immediate loading, progressive loading, and delayed loading
The dimensional planning for dental implants includes considerations for minimum distances between implants and adjacent teeth, minimum bone thickness, and orofacial implant position.
The orofacial implant position should be chosen to optimize the screw channel location, and the implant shoulder should be sinked around 1~1.5mm subcrestally with a sloping crest for prosthetic components.
Prosthodontic principles should be applied in the surgical placement of dental implants.
The minimum mesiodistal distance between implants and adjacent teeth at the bone level is 1.5mm and 3mm for adjacent implants.
The bone layer for implant positioning should be at least 1-2mm thick.
The orofacial implant position and axis should be chosen to optimize screw channel location, with the anterior position being behind the incised edge and the posterior position at the center.
The coronoapical implant position requires the implant shoulder to be sinked around 1~1.5mm subcrestally and the crestal bone to be in a sloping edge.
