Retaining natural roots under the denture base helps preserve alveolar bone, enhances proprioception, and improves prosthesis stability. This case report describes the rehabilitation of a 76-year-old man with osteoporosis on long-term bisphosphonate therapy, type 2 diabetes, and hypertension. Due to the high risk of medication-related osteonecrosis of the jaw (MRONJ), implant placement was contraindicated. A maxillary overdenture retained by custom O-ball attachments on multiple remaining roots was chosen as a minimally invasive and cost-effective treatment. The prosthesis provided excellent retention, stability, and patient satisfaction, successfully resolving issues experienced with previous conventional dentures. This case highlights the value of utilizing existing teeth with custom attachments to achieve functional and predictable overdenture outcomes in medically compromised patients.<\/jats:p>","DOI":"10.4103\/ijdr.ijdr_353_25","type":"journal-article","created":{"date-parts":[[2026,2,27]],"date-time":"2026-02-27T18:00:11Z","timestamp":1772215211000},"page":"493-496","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Tooth-Supported O-Ball Retained Maxillary Overdenture in a Patient Contraindicated for Dental Implants Due to Bisphosphonate Therapy"],"prefix":"10.4103","volume":"36","author":[{"given":"Aruna","family":"Wimalarathna","sequence":"first","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dental Sciences, University of Peradeniya, Sri Lanka"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,2,27]]},"reference":[{"key":"R1-20260325","doi-asserted-by":"crossref","first-page":"327","DOI":"10.11607\/ijp.8278","article-title":"Impact of removable partial dentures on masticatory performance in partial edentulism:A systematic review","author":"Yaparathna","year":"2024","journal-title":"Int J Prosthodont"},{"key":"R2-20260325","first-page":"1","article-title":"The global prevalence of osteoporosis among the world older adults:A comprehensive systematic review and meta-analysis","volume":"16","author":"Salari","year":"2021","journal-title":"J Orthop Surg Res"},{"key":"R3-20260325","first-page":"66","article-title":"Prevalence of osteoporosis among men in Sri Lanka:A community-based study","volume":"54","author":"Lekamwasam","year":"2009","journal-title":"Ceylon Med J"},{"key":"R4-20260325","first-page":"34","article-title":"Osteoporosis in urban males over 50:Evaluation by DEXA","volume":"19","author":"Karunanayake","year":"2010","journal-title":"Sri Lanka J Med"},{"key":"R5-20260325","doi-asserted-by":"crossref","first-page":"1938","DOI":"10.1016\/j.joms.2014.04.031","article-title":"American Association of Oral and Maxillofacial Surgeons position paper on medication-related osteonecrosis of the jaw\u20142014 update","volume":"72","author":"Ruggiero","year":"2014","journal-title":"J Oral Maxillofac Surg"},{"key":"R6-20260325","first-page":"780","article-title":"Evaluation of residual ridge resorption in overdenture patients with retained roots","volume":"124","author":"Shah","year":"2020","journal-title":"JProsthet Dent"},{"key":"R7-20260325","first-page":"295","article-title":"Patient-reported outcomes of overdentures versus conventional dentures:A systematic review and meta-analysis","volume":"30","author":"Bidra","year":"2021","journal-title":"JProsthodont"},{"key":"R8-20260325","doi-asserted-by":"crossref","first-page":"920","DOI":"10.1016\/j.joms.2022.02.008","article-title":"American Association of Oral and Maxillofacial Surgeons'Position Paper on Medication-Related Osteonecrosis of the Jaws-2022 Update","volume":"80","author":"Ruggiero","year":"2022","journal-title":"J Oral Maxillofac Surg"},{"key":"R9-20260325","first-page":"2891","article-title":"Clinical performance of attachment-retained overdentures:A 5-year prospective study","volume":"23","author":"Koutayas","year":"2019","journal-title":"Clin Oral Investig"},{"key":"R10-20260325","first-page":"327","article-title":"Effectiveness of tooth-supported overdentures in medically compromised patients:A systematic review","volume":"37","author":"Maia","year":"2020","journal-title":"Gerodontology"}],"container-title":["Indian Journal of Dental Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/ijdr.ijdr_353_25","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,26]],"date-time":"2026-08-26T18:45:58Z","timestamp":1787769958000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/ijdr.ijdr_353_25"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,10]]},"references-count":10,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2025]]}},"URL":"https:\/\/doi.org\/10.4103\/ijdr.ijdr_353_25","relation":{},"ISSN":["0970-9290","1998-3603"],"issn-type":[{"value":"0970-9290","type":"print"},{"value":"1998-3603","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,10]]},"assertion":[{"value":"2025-05-25","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-11-28","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
