What does “Alveolar ridge preservation (socket preservation)” mean?
Alveolar ridge preservation aims to limit changes in bone width and height after a tooth is extracted. Methods include placing graft material in the socket and using a covering material when needed. It is also called socket preservation.
Consider post-extraction changes and future treatment together
Bone and gum contours may change as an extraction site heals. Preservation is an option intended to help maintain the shape for future restoration. First establish whether the tooth can be saved and why extraction is needed, then plan what treatment will follow and when.
Ask about purpose and suitability rather than the material name alone
Grafts differ in origin and properties, and the type or need for a covering membrane can vary. Filling the socket does not instantly turn the material into your own mature bone. The bone walls, soft tissues, wound care, and healing also need assessment.
Reassess bone requirements after healing
The 2021 Cochrane review suggested that preservation may reduce loss of bone width and height after extraction, but judged the evidence for this effect to be very uncertain. Its effects on the need for further augmentation and on implant outcomes were also uncertain. Bone at the intended implant position must still be reassessed. No material should be described as best for everyone.
Frequently Asked Questions
Does socket preservation mean I will not need a later bone graft?
That cannot be guaranteed. Further reconstruction may be needed depending on the bone volume and shape after healing and the planned implant position.
Does everyone need it when a tooth is removed?
It is not decided uniformly for every extraction. The team weighs socket walls and gums, future treatment timing and restoration, the burden of treatment, and what it can reasonably achieve.
