Preservation of the alveolar ridge with hydroxylapatite tooth root substitutes. 1985

J H Quinn, and J N Kent, and R G Hunter, and C M Schaffer

A total of 49 patients, who were followed for 3 to 31 months, have had 92 hydroxylapatite root implants placed in fresh extraction sockets without soft tissue closure. Hydroxylapatite root implants maintain approximately twice as much alveolar bone as the contralateral control sites without implants. It is believed that this method is a more effective and efficient procedure to preserve alveolar bone for retention of dentures than previously described procedures.

D006882	Hydroxyapatites	A group of compounds with the general formula M10(PO4)6(OH)2, where M is barium, strontium, or calcium. The compounds are the principal mineral in phosphorite deposits, biological tissue, human bones, and teeth. They are also used as an anticaking agent and polymer catalysts.

D014092	Tooth Root	The part of a tooth from the neck to the apex, embedded in the alveolar process and covered with cementum. A root may be single or divided into several branches, usually identified by their relative position, e.g., lingual root or buccal root. Single-rooted teeth include mandibular first and second premolars and the maxillary second premolar teeth. The maxillary first premolar has two roots in most cases. Maxillary molars have three roots.
