What follows the extraction of first molars in terms of bone resorption?

After the extraction of first molars, the pattern of bone resorption varies between the maxilla and mandible due to anatomical and physiological differences. The selected answer highlights that more resorption occurs on the palatal side of maxillary molars.

This phenomenon can be attributed to several factors, including the unique structure of the maxillary sinus and the presence of cancellous bone, which influences the resorption pattern. When a maxillary molar is extracted, the loss of the tooth’s root support can lead to a greater degree of bone loss on the palatal side because this side is often not as structurally fortified compared to the buccal side. The palatal bone is generally thinner and less dense, making it more susceptible to resorption after tooth loss.

Understanding this localized resorption pattern is essential in clinical practice, as it can impact decisions regarding prosthetic rehabilitation and maintenance of surrounding hard and soft tissue stability. While other areas may experience resorption as well, the palatal side of maxillary molars specifically has been studied and observed to show more significant bone loss in the aftermath of an extraction.
