Ultimate Guide to Implant Surface Treatment Techniques

(1)Mechanical processing (machining, such as Br? Nemark system) is the earliest form of implant surface treatment. Although there have been reports of success over the years, the speed of integration with bone tissue is not as fast as that of the implant system with rough treatment. treatment, so the trend for this treatment modality is waning.

(2) The Nemark system is also mainly based on surface oxidation (TiUnit). It is sandblasted, coarse-grained and acid-etched. Any titanium material in contact with air will quickly form an oxide layer on the surface, so surface oxidation treatment refers to the formation of a porous oxidized surface during the oxidation process and the formation of a variety of factors.

(3) Currently, this approach is more successful in the market with NobelBiocare’s TiUnit treatment. way. it

(4) and titanium slurry spraying (Titaniumplasmassprayed, TPS). Such treatments as ITIGroup system) have been gradually replaced by SLA. The ITI system was mainly based on the early stages of TPS surface treatment, but has now been changed to SLA surface treatment. it

(5) Hydroxyapatite coating (hydroxyapatite, HA). For example, SulzerCalcitek system)

(6)multi-layered spherical structure on the surface (beads on a string, such as Innnova's Endopore system). it

(7)Hybrid type (hybrid type). Currently, in many implant systems, two or more types of treatments are involved on the implant surface.

Osseointegration theory One of the main points proposed by the osseointegration theory is to ensure the healing of the bone without external interference, and if the implant is placed throughout the bone healing period, fibrous healing (rather than osseointegration) is possible Produced by external forces. Especially when a bone graft is implanted at the same time during the implantation process, primary healing in a sterile state can be guaranteed to the greatest extent under closed conditions. so

The distance between the upper edge of the implant and the gingival margin is the distance between the upper edge of the implant and the gingival edge and depends on the depth of the ferrule. This distance is related to the thickness of the mucoperiosteum and the depth of the implant. There are certain differences between individuals and cuff thickness. The edge is located approximately 1mm below the gums. It ensures that it does not form deep periodontal pockets and ensures aesthetic results in the gum area. So it is more suitable for the front teeth area with higher aesthetic effect.
