Ectodermal Dysplasia (ED) is a rare genetic disorder characterized by the aberrant development of ectodermal structures, presenting complex dental, dermatological, and psychological challenges. This case report focuses on a 7-year-old male with ED, delving into his prenatal, natal, and postnatal history, medical and dental records, clinical examination findings, and the subsequent treatment plan. The patient exhibited classical ED features, including missing teeth, dry and fragile skin, prominent lips, cranial abnormalities, reduced facial height, and an enlarged tongue. A multidisciplinary team approach was pivotal in addressing the intricate dental complications associated with ED. Preventive measures such as meticulous oral hygiene, periodic high-fluoride applications, and resin-modified glass ionomer fissure sealants were administered. Prosthodontic interventions were designed to restore function and aesthetics, including upper partial denture and lower overdenture. This case underscores the significance of early and comprehensive dental intervention in ED patients, emphasizing the vital roles played by pediatrics, orthodontics, prosthodontics, surgery, and periodontics in achieving favorable outcomes. Furthermore, it highlights the psychosocial challenges faced by ED individuals, emphasizing the need for holistic care and support.

Current scientific growths for implant over-denture attachments. We focused on the following topics: attachment systems, retention of various attachments, stress distribution with different attachments, the design and fabrication of attachments, digital techniques in over denture attachments, and the effects of attachments in two-implant health. We found that plastic resin is commonly used for ball and bar attachments, whereas nylon resin is commonly used in locator attachments. The locator system offers a valuable attachment option for implant-retained over denture. Attachment retention reduces while lateral force increases with implant inclination in over denture. The higher the retention of an over-denture attachment, the higher the transferred stresses. Additionally, clip loading produces more stress in implants and precision elements than bar-retained dentures.

Satisfactory restoration in a patient with a partially edentulous situation can be challenging especially when bilateral posterior segment of teeth is missing. Combined prosthesis still have a good place as a treatment option for partially edentulous Kennedy's class I conditions especially when implants are contraindicated for one reason or another. With proper case selection and treatment plan, precision attachments system can be used to improve retention and esthetics. The purpose of this article was to describe a case of a patient with extended Kennedy's class I condition, which was prosthetically restored by a combined prosthesis using a extracoronal precision attachment.
