Introduction:

Lichenplanus is considered a chronic mucocutaneous disease, in which etiopathogenesisis considered a autoimmune disorder, with a prevalence between 0.5 and 2%. Placing dental implants in patients with this disease can change the success of the treatment.

Material and Method:

A search was made in the Pub Med and Med line database, using as keywords: "lichen planus" and "dental implant". The inclusion criteria was studies in humans with oral lichen planus who had been treated with osseo integrated dental implants published in English, which are observational, experimental or clinical cases published between 1990 and 2020.

Results:

A total of 13 articles are selected, the N of implants was 362 implants placed in 148 patients. The follow-up of the implants is from 2 to 10 years. There is a failure of 45 (12,43%) implants, of which 42 occurs in patients with active lichen planus and 3 in a erosive lichen without specifying if they are in the active phase or not. The failure rate was higher in women (61%) compared to men (44%). In one case, oral squamous cell carcinoma [OSCC] is diagnosed 3 years after implant placement, which corresponds to 0.2% of cases.

Conclusion:

oral lichen planus is an auto immune disease that we must take into account when we place implants and control periodically.
