“…Both have been studied following their implantation in man and animals under a variety of situations, e.g. to fill surgically created defects in bone (Jarcho et al 1977, Heimke & Griss 1983, Beirne & Greenspan 1984, to fill osseous defects resulting from inflammatory periodontal disease (Rabalais, Yukna & Meyer 1981, Froum et al 1982, Moscow & Lubarr 1983, Yukna, Meyer & Brite 1984, Kenney et al 1985, Baldock et al 1985, West & Brustein 1985 and to augment the edentulous ridge (Ogiso et al 1980, Kent et al 1982, 1984, Ailing 1984, Rothstein, Paris & Saye 1984. However, as far as periodontal defects are concerned, there is no evidence of bone formation being stimulated by the placement of dense hydroxyapatite (Froum et al 1982, Moscow & Lubarr 1983.…”

A TEM study was made of the response to synthetic hydroxyapatite prepared in powder form and implanted for 6 and 12 months respectively in infrabony lesions in 2 adult patients with chronic periodontitis and tooth mobility. Round or oval‐shaped crystal aggregates, ranging in diameter from 1 to 20 μm, were surrounded by connective tissue free of inflammatory cells. The aggregates were made up of loosely‐packed individual synthetic hydroxyapatite crystals, with a mean diameter of 128.12±14.57 nm, separated by an amorphous matrix containing few collagen fibrils. In the 6‐month implants small apatite crystals, of a size similar to those found in adjacent alveolar bone and giving similar diffraction patterns, appeared in the center of the aggregates between the relatively large crystals of synthetic hydroxyapatite. These new apatite crystals filled the amorphous matrix progressively from the center to the periphery of the aggregate. The latter was surrounded either by fibroblasts or by osteoblasts and osteoid tissue. In the 12‐month samples a calcified collagenous bone matrix enveloped the crystal aggregates. Typical osteoclasts, lacking a brush border, were evident around certain aggregates. Some osteoclasts contained large vacuoles filled with synthetic hydroxyapatite crystals.

“…hydroxyapatite (HA) for filling of bone defects and creation of the residual ridge (6)(7)(8)(9)(10)(11). However, it is as difficult for cells to invade this material as it is for them to infiltrate many of the block and paste-formulation bone filling materials; therefore, these materials persist for a long time, putting patients at increased risk of secondary infection (12,13).…”

The aim of this in vivo study was to evaluate the utility of bone graft gel containing hydroxyapatite nanoparticles in promoting bone regeneration in a mouse model of vertical bone augmentation. Materials and Methods: Gel implants with high and low viscosity were compared for their bone regenerating ability. Bone formation at 12 weeks and material reactions were observed radiographically and histologically. Results: Radiological analysis showed that most bone augmentation area in the graft material occurred in the fourth week after surgery regardless of the viscosity of the gel, and then gradually decreased. The volume of bone augmentation area was greater in the high-viscosity implant group than in the lowviscosity implant group at all time points, the difference was statistically significant at 8 and 12 weeks. Histological evaluation indicated that the new bone area was significantly smaller in the high-viscosity implant group. Conclusion: Gelatinous graft materials containing hydroxyapatite nanoparticles were confirmed to be useful in vertical bone augmentation.Graft materials used for formation of bone tissue in dentistry include autologous bone, allogeneic bone, xenograft tissue, and artificial bone (1-5). Although many approved bone substitute materials are granular, problems remain concerning operability and dissemination to surrounding tissues. There are several clinical reports on the use of granular 1053 This article is freely accessible online.

“…Subperiosteal tunnels were created in the areas of the defects and the open barrel of a tuberculin syringe was loaded with the hydroxyapatite granules mixed with a saline solution, which was then injected into the tunnels (Figure 2). 9 The result of the augmentation is visible in the orthopantomograph presented in Figure 3. The mandibular denture was relined initially with a tissue conditioner.…”

“…During a consultation, with an oral surgeon, it was suggested that she might benefit from hydroxyapatite augmentation of the posterior mandibular ridge. It has been reported that hydroxyapatite may be used to fill concavity‐shaped defects on the medial and lateral surfaces of residual alveolar ridges 9 . After discussion with the patient, the granules were surgically placed beneath the periosteum on each side of the posterior mandibular ridge.…”

Treatment of an edentulous patient over 23 years showing the influence of systemic health on oral health and quality of life

This case history follows the treatment of a 61‐year‐old edentulous woman over a period of 23 years. The patient was wearing complete dentures for 25 years prior to treatment, was in pain, and having difficulty eating. Many treatments were tried, including multiple soft liners, hydroxyapatite to improve her mandibular ridge, and finally an implant‐supported‐overdenture. However, in spite of using all the technical procedures and materials available to us at the time of treating the patient, we were unable to sustain the comfort and quality of life for this patient. This happened because of the severe resorption of her mandible, with an intolerance to occlusal loading, and the continuous deterioration of her systemic health.
