Objectives: Periodontal Ehlers-Danlos syndrome (pEDS) has recently been delineated as a molecularly defined cause of early severe periodontitis. Here we report that implant treatment failed in three affected individuals from one family.
Materials and methods: Longitudinal data before and after implant treatment were examined for three individuals with genetically confirmed pEDS in the course of a large-scale pedigree analysis.
Results: Most detailed information was available for individual 1 in whom first periodontal bone loss was diagnosed at age 16 years. Rapid progression resulted in multiple tooth extractions at age 23 years and interforaminal placement of four implants. After primary implant success, peri-implant bone loss accompanied by highly inflamed tissues and receding gums led to explantation five years later. In individual 2, severe periodontitis was diagnosed at age 15 years and resulted in extraction of all mandibular teeth at age 28 years. Four interforaminal implants were placed. Peri-implant bone loss was diagnosed four years later, when up to three implant threads were exposed. Individual 3 showed complete tooth loss at age 29 years. He was restored with ten implants and removable prosthesis. Peri-implant bone loss was diagnosed radiologically eight years later, when seven implant threads were exposed.
Conclusion: This is the first report on severe peri-implant bone loss in pEDS. Retention of teeth as long as possible is the primary objective in pEDS as satisfying prosthetic solutions are missing. Further evaluation of dental management in individuals with pEDS is needed to develop concise treatment guidelines.
