What is the main factor when deciding to increase the occlusal height for oral reconstruction?

When considering an increase in occlusal height during oral reconstruction, the primary focus is on ensuring that the inter occlusal distance remains physiologically acceptable. This aspect is crucial because if the inter occlusal space is too large or too small, it could lead to functional issues, such as improper occlusion or interference in lateral movements, which can adversely affect the patient's bite and overall oral health.

Inter occlusal distance must accommodate not only the structural and aesthetic considerations but also ensure that the biomechanics of chewing and other functions remain intact. An increase in occlusal height needs to maintain a comfortable and functional relationship between the maxillary and mandibular arches, thus allowing for effective mastication and minimized strain on the temporomandibular joints.

While factors such as tooth bulk for retention, the condition of the alveolar process, and aesthetic concerns are also pertinent to the overall decision-making process in oral reconstruction, the physiological acceptability of the inter occlusal distance is the foremost consideration impacting function and patient comfort.
