The typical case for half-mouth dental implants is 4 to 6 implants. The number of dental implants in the lower half of the mouth depends on the individual. Lower jaw bone is more dense, the lower half of the mouth dental implants 4 can usually achieve good retention effect. The bone in the upper jaw is more sparse, and the upper half of the mouth should have at least 4 dental implants, which can be increased to 6 for stability. If the alveolar bone is in poor condition, the number of implants can be increased appropriately in order to better share the biting force. Although generally 4 to 6 implants are sufficient for the upper or lower half of the mouth, the number of implants can be increased appropriately in order to achieve a better bone position or to bear a large biting force, and you can consult with your dentist for details.
