Srapping Hydroxyapatite Implants
Ophthalmic Surgery, Lasers and Imaging Retina, 1999Abstract: Hydroxyapatite (HA) implants currently are most commonly wrapped in fresh unprocessed human donor sclera before implantation to facilitate entry into the orbital space and allow extraocular muscle attachment. Autologous temporalis fascia or autologous fascia lata are alternatives, but prolong surgery time and require a second operative site ...

Thermoluminescence in hydroxyapatite
Medical Physics, 1979A thermoluminescent (TL) glow peak has been shown to exist at 80°C in synthetic hydroxyapatite, in amorphous calcium phosphate, and in deproteinated rat bone mineral. This TL glow peak is excited by a thermal pretreatment at elevated temperature, followed by exposure to ultraviolet (UV) light. When measured on a cylic TL‐readout UV‐exposure basis after

Hydroxyapatite Chromatography (HAC)
2023Hydroxyapatite (HA) is a mixed-mode media that has been used extensively for the purification of proteins and DNA since the 1950s. Hydroxyapatite possesses a distinctive selectivity that may be applied in the purification of a wide range of biomolecules: immunoglobulins, alkaline proteins, acidic proteins, and DNA.

Calcium Hydroxyapatite Fillers
Facial Plastic Surgery, 2011Calcium hydroxyapatite fillers have unique advantages over other fillers in regards to duration of action and volume of product required for augmentation, especially in the midface and lower face. In this article, we describe our experience with calcium hydroxyapatite fillers and compare them with other available filler products.

Comparison of hydroxyapatite and hydroxyapatite tricalcium-phosphate coatings
The Journal of Arthroplasty, 2002This study compared the effects of hydroxyapatite (HA) coating and biphasic HA/tricalcium-phosphate (HA/TCP) coating on the osseointegration of grit-blasted titanium-alloy implants. Each coated implant was compared with uncoated grit-blasted implants as well.
