As growth of the alveolar bone continues and the adjacent permanent teeth erupt, the ankylosed deciduous tooth appears to submerge into the bone, although in reality it has not changed position. Treatment is by extraction of the involved tooth, to prevent malocclusion , periodontal disturbance or dental caries .
The dental sac or follicle gives rise to three important entities: cementoblasts, osteoblasts, and fibroblasts. Cementoblasts form the cementum of a tooth. Osteoblasts give rise to the alveolar bone around the roots of teeth. Fibroblasts are involved developing the periodontal ligament which connect teeth to the alveolar bone through cementum. [9]
At present, guided bone regeneration is predominantly applied in the oral cavity to support new hard tissue growth on an alveolar ridge to allow stable placement of dental implants. When bone grafting is used in conjunction with sound surgical technique, guided bone regeneration is a reliable and validated procedure.
The formative role of the dental follicle starts when the crown of the tooth is fully developed and just before tooth eruption into the oral cavity. [2]Although tooth eruption mechanisms have yet to be understood entirely, generally it can be agreed that many factors, together, affect the tooth eruption process which is why it is very difficult to differentiate the causes and effects.

We see bone resorption happening on the outer side of the "V" of the bone and bone deposition happens on the inner side of the "V". Therefore, the movement of bone happens towards the open-end of the V. Enlow's Counterpart Principle [12] states that growth of one bone in the craniofacial area relates to the other bones in the same region ...
It provides bone for teeth to erupt into and to allow implants to be placed as a possible future treatment option. The procedure should be carried out before the upper canine has erupted. Ideally the root of the canine should be one to two-thirds formed and that there is a space available to place the bone graft.
Orthodontics [a] [b] is a dentistry specialty that addresses the diagnosis, prevention, management, and correction of mal-positioned teeth and jaws, as well as misaligned bite patterns. [2] It may also address the modification of facial growth, known as dentofacial orthopedics. Abnormal alignment of the teeth and jaws is very common.
Torus mandibularis is a bony growth in the mandible along the surface nearest to the tongue. Mandibular tori usually are present near the premolars and above the location on the mandible of the mylohyoid muscle attachment. [1] In 90% of cases, a torus is on both inner sides of the mandible (left and right); however, they may differ in size.
