Use of collagen tubes containing particulate hydroxylapatite for augmentation of the edentulous atrophic maxilla: a preliminary report.
Collagen tubes of specific configuration containing particulate hydroxylapatite were placed by a palatal approach to augment edentulous atrophic maxillas. Both the ability to chew and comfort of the denture were improved in the 12 reported cases. Eleven cases showed solidification of the implant between 8 and 16 weeks. There was no problem with particle migration or loss of vestibular height.
