Implant Overdenture

With the continuous development of oral science, implant technology has gradually replaced traditional denture restoration. Implants have their unique advantages: no foreign body sensation, comfortable, beautiful, and will not cause alveolar bone resorption. However, implanting a full mouth of teeth is relatively expensive, and many elderly people cannot accept it. This is how the implant overdenture restoration method came into being.
Simply put, implant overdentures are implants implanted under traditional full dentures, which fix the full dentures through a special connection method, and patients can take them off and wear them by themselves. According to the patient’s intraoral alveolar bone conditions, the number and location of implants can be flexibly selected, and generally 2 to 6 implants are required.

• Implant overdentures are an excellent treatment option for edentulous patients.
• This type of restoration can be used when fixed implant restorations or complete dentures do not meet the patient’s needs.
• It is fixed by placing attachments directly on the implant or bar superstructure.

Adequate cleaning, hygiene measures and maintenance of removable dentures and intraoral fixed components are essential for long-term clinical success.

Advantages and basic considerations of implant overdentures

When considering the realization of aesthetics, pronunciation and convenience of oral hygiene, some patients with soft and hard tissue defects cannot be solved by fixed implant restorations. For these patients who are troubled by the incomplete function of full dentures, implant overdentures provide the necessary fixation and stability in a way that meets the aesthetic, pronunciation and functional requirements, and can replace the defective hard and soft tissues.

Patients treated with implant overdentures have much higher scores in chewing ability, function and quality of life than those wearing traditional full dentures. In addition, due to the movable nature of the restoration, it is easier to perform oral hygiene than fixed implant restorations.

Implant overdentures are often used for those with severe alveolar bone atrophy and absorption, those who are prone to fall off and cannot function well with traditional full denture restoration methods, those who can only implant a small number of implants in the remaining alveolar bone, those with severe disharmony between the upper and lower dental arches, those who find it difficult to restore beauty and pronunciation with implant fixed restorations, and those who cannot afford the high cost of surgery. Implant overdentures are more suitable for those who choose implant overdentures.

Compared with traditional full dentures, implant-supported overdentures have better retention effects, are less likely to loosen and fall off, and chewing efficiency is increased by 20%. Implant placement can reduce the absorption of the surrounding residual alveolar bone. Compared with implant-supported fixed dentures, the denture base of implant-supported overdentures can provide good support for the lips, cheeks and maxillofacial soft tissues, and is easy to remove for cleaning and maintenance, and is relatively inexpensive.
