The benefits of dental implants are both aesthetic and structural. Dental implants look and feel like your own teeth. Because they integrate with your bone they prevent the bone loss and gum recession that often happens with bridgework or dentures. Dental implants are also more secure without the need for paste or glue like dentures, and give you confidence when eating or speaking.
Dental implants are also beneficial to your remaining natural teeth because they put less pressure on surrounding teeth and remaining teeth do not have to be altered as they would with a standard bridge.
In some cases, particularly in the upper back jaw, it can be difficult to place implants due to bone quantity and the close proximity to the sinus. In this case sinus augmentation - raising the sinus floor - maybe necessary. If deformities in the jaw mean you do not have enough bone to fit the implants, your dentist may recommend ridge modification where bone or bone substitute will be filled under the gum.
