The knowledge of how inflammatory periodontal destructive processes occur has been improved and expanded over the past years. It is the tissue response itself, caused by microbial irritation from subgingival biofilm, that leads to the destruction of the marginal periodontium and also shows systematic effects as chronic periodontitis. New therapy approaches have therefore often been developed to complement mechanical therapy. These have themselves made major progress in terms of methodology and instruments. The contemporary demand for the preservation of tissue with regeneration potential, has led to the replacement of generous periodontal flap surgery with graceful, reconstructive and repairing methods that are capable of satisfying even the highest aesthetic standards. However perio therapy, as well as endo therapy, also have their limits. Teeth are removed and replaced by implants.

The favourable assessment of the quality and quantity of the alveolar bone as well as the thickness of the mucosa with appropriate modern methods is the primary prerequisite for the correct insertion and problem-free placement of implants in edentulous jaw sections. If therapeutically necessary, the perfect anchoring of implants of the jawbone and/or peri-implant mucosa should be preceded by the enhancements using plastic perio-surgery methods. The minimum thickness is determined by the short- and long-term biological reactions in the peri-implant soft and hard tissue and is absolutely necessary. There are also processes in the mucous membrane and the peri-implant bone –caused by microbial biofilm – that can be compared to those in the marginal periodontium. However, due to micromorphological differences, the deficiently conditioned peri-implant soft tissue reacts more intensively, the inflammatory processes are much more difficult to control, and they spread much faster into deeper tissues.

All periodontal therapeutic measures and implants, without exception, require personal and professional follow-up care. The daily oral hygiene includes mechanical, hydrodynamic and chemical aids, in accordance with the patient’s manual abilities. Professional follow-up care is always required and should occur at regular intervals, even in the case of patients with good oral hygiene.
