Predictable Single-Tooth Peri-Implant Esthetics: Five Diagnostic Keys

Single-Tooth Peri-Implant Esthetics: Five Diagnostic Keys - Dental CE Course
Launch Course

Course Objectives (2 CE Credits)

John C. Kois, DMD, MSD

To more accurately predict the peri-implant esthetic outcome before removing a failing tooth, an understanding of five diagnostic keys is essential. Ultimately, the predictability of peri-implant esthetics may be determined by the patient's presenting anatomy rather than the clinician's ability to manage state-of-the-art procedures. This article by Dr. John C. Kois discusses the following diagnostic keys:

  • Relative tooth position
  • Form of the periodontium
  • Biotype of the periodontium
  • Tooth shape
  • Position of the osseous crest


Each of the five diagnostic keys is intimately related to the others. These diagnostic keys will enable the clinician to develop treatment options and clinical procedures that are more specific to the desired therapeutic outcome.

CAUTION: When viewing the techniques, procedures, theories and materials that are presented, you must make your own decisions about specific treatment for patients and exercise personal professional judgment regarding the need for further clinical testing or education and your own clinical expertise before trying to implement new procedures.
