Abstract EN

Introduction: Papillon-Lef`evre syndrome (PLS) is an autosomal recessive disorder.

It is characterized by generalized rapid destruction of the dental alveolar supporting bone and hyperkeratoses of the palms and soles.

It affects both the primary and permanent dentition, so patients are usually edentulous at early age and require prosthodontic treatment.

Dental implants are a predictable treatment option for replacing missing teeth.

It has strong survival and successful outcomes; and enhance support, stability, and retention of prostheses.

Purpose : The aim of this study was to assess osseointegrated dental implants in patients with papillonlef`evre syndrome using different methods of prostheses .

Methods : Between the years 2011 and 2015, 5 Papillon-Lef`evre syndrome patients (1 male and 4 females) with a mean age of 23,4 years (ranging, 22 to 26 years) participated in the study.

Twenty-eight Osstem dental implants with a height of 11,5 - 13 mm and a diameter of 4 mm – 5 mm were inserted into the residual bone.

After a healing period of 4- 5 months, abutment connection was applied, and the implants were tested clinically in all patients.

Prosthetic treatment with fixed and implant-retained overdenture prostheses were provided.

The mean follow-up time was 2,7 years ( 2 - 4 years ).

Results : Patients tolerated the procedure well and no complications happened after surgical treatment .

Of the 28 dental implants placed, no implant was lost during the period of follow-up of 2 - 4 years giving an implant survival rate of 100% .

Implants were clinically stable and preserve the alveolar bone with no complication except for some cases of peri-implant mucositis .

Patients presented significant improvement in oral function and psychosocial activities with no prosthetic complications.

Conclusion: This study demonstrates that patients with Papillon-Lef`evre syndrome can be treated successfully by dental implants with deferent prosthetic methods, and the extraction of hopeless teeth preserves the alveolar bone in these patient and enables us to use long implants and implant-supported fixed prosthesis.
