most commonly , contractures arise where adequate burn care and delivery have not occurred and scar management has not been instigated in a vigorous manner . repair by regeneration can no longer occur when the depth of injury extends beneath the reticular dermis , and healing by secondary intention.1 the resultant wound contraction can lead to contractures over flexor surfaces and its surroundings . for example , limitation of opening jaws may cause difficulties in accessing the dentitions and tissues of the oral cavity , and in using full size of removable denture for the patients . telescopic implant - supported removable partial prosthesis with milled abutments has been used for the patient with burn contracture to provide enough retention and stability for the prosthesis . a 60-year old woman was referred from the plastic surgery department to the department of prosthodontics at yonsei university health system . she had a chief complaint of restoring her oral function and esthetics after series of plastic skin graft procedure done . during the extra oral examination it was noted that the elasticity of muscle and skin tissue around oral angular area was lost due to scars from burns and tissue grafting , which resulted in limited maximum mouth opening of 20 mm . therefore , proper prosthodontic treatment was impossible on the right quadrants of the mouth ( fig . the intraoral examination showed that all of maxillary teeth were missing except tooth number # 25 and splinted gold crowns on # 34 and # 35 , whereas fixed partial denture on # 33 to # 43 were present on the mandible . in order to restore the patient 's masticatory function , prosthodontic treatment plan of using 4 implants on the left quadrants each of two implants were placed on upper and lower posterior left jaws , however no implant on anterior ridge were possible due to severe atrophy of the maxilla . anterior cantilever type removable partial denture was planned to meet patient 's esthetic demand , which consists of a telescopic crown abutment on # 25 and two implant supported abutments on area of # 26 and # 27 in the maxillary area ( fig . 2 ) . on the mandible , implant - supported fixed partial denture on area of # 36 and # 37 was planned . the implants ( strauman basel , switzerland ) ( 4.810 mm ) were placed on predetermined area accompanied with sinus lift ridge augmentation procedure and proper follow up was performed during the 6 month healing period of time . customized abutments were fabricated on implants and designed in the predetermined angle paralleling to the prepared tooth of # 25 ( fig . 3 ) . removable partial denture was inserted to verify phonetics , esthetics and function . key and keyway rigid attachment was used for retention and ledge type rest was used for support ( fig . no complications have occurred in 5 years since the insertion of the prostheses ( fig . removable type of prosthesis was selected as treatment option after considering the factors of oral hygiene maintenance and lip support of patient to improve esthetics . because there was only one natural tooth in the maxilla , we , therefore , had to improve the unfavorable removable partial denture using implants.2 due to the lack of anterior ridge , the implant option on anterior ridge was deemed unavailable , and natural tooth was splinted with implant to support anterior cantilevered prosthesis . combining implants with natural teeth is controversial because of the variations in movement during function.3 a lot of complications regarding implant and tooth - supported prosthesis may arise ; including fracture of the prosthetic components , intrusion of the natural tooth , marginal bone loss , and loss of osseointegration,4 but survival rates of implant and tooth - supported fixed prostheses are comparable to implant - supported fixed prostheses.5 there was no prosthetic complication in implant - and tooth - supported fixed prosthesis in this case . in this case , forces in the cantilevered area were transmitted to the abutments , causing tilting and rotational movements,6 but cantilevered prostheses are preferable when reduced stress is inherent.6,7 the prosthesis in this patient is expected to have a good prognosis since it is designed with hypoocclusion in anterior areas .
