[Edentation of the 6-year molar tooth. Clinical aspects and treatment]

The problem of the 6 year molar tooth edentation has been approached from an unilateral point of view. The present paper deals with the complex factors that contribute to the onset and evolution of the 6 year molar tooth edentation. The group studied included 2000 subjects making it possible to establish the frequency of the affection in terms of age, general condition of the body environmental factors, caries prevention, out-patient follow up, previous dental treatment. The study continued with 100 cases of molar edentation without prostheses, establishing the clinical and complementary signs of the 6 year molar syndrome. Likewise discussed are the favourable elements and errors in the concept and treatment of previously applied prostheses. A complex treatment was applied in 50 cases of 6 year molar edentation showing the preprosthetic, proprosthetic and prosthetic treatment applied and certain therapeutical techniques applicable by the practitioner.
