Hyperalgesia
Increased pain response to a normally painful stimulus. An increased sensitivity to pain, which may be caused by damage to nociceptors or peripheral nerves. An excessive sensitivity to pain; the opposite of hypalgesia. Decreased threshold to a normally painful stimulus. An increase in pain sensitivity such that normally painful stimuli feel even more painful. An…

Hypalgesia (hypoalgesia)
Reduced sensitivity to pain that results from a raised pain threshold. A lessened sensitivity to pain; the opposite of hyperalgesia.

Hygienic (sanitary) pontic
A pontic (suspended crown in a fixed bridge) that is simpler to clean because it has a rounded or bullet‐shaped cervical form and does not contact the edentulous ridge. Producing healthy conditions.
-
Hygiene cap (syn)
Comfort cap, healing abutment, healing cap, sealing screw. Component inserted over a prosthetic abutment. Its function is to prevent debris and calculus from invading the internal portion of the abutment between prosthetic appointments.
-
Hydroxyethyl methacrylate (HEMA)
Alloplastic material made of hydrosoluble monomer, which can polymerize under various circumstances at low temperatures. It can be used to prepare various hydrogels to immobilize proteins or cells for grafting purposes.
-
Hydroxyapatite implant surface
Primarily insoluble or partially soluble amorphous and crystalline calcium phosphate coating applied to the surface of an implant, intended to enhance osseointegration.
-
Hydroxyapatite ceramic
A composition of calcium and phosphate in physiologic ratios to provide a dense, nonresorbable, biocompatible ceramic used for dental implants and residual ridge augmentation.
-
Hydroxyapatite‐bone grafting
Method of grafting in which granules of hydroxyapatite can be added to chips of autogenous bone to obtain the desired shape and compromise or delay resorption.
-
Hybrid prosthesis (syn)
High‐water prosthesis. A screw‐retained, metal‐resin, implant‐supported, fixed complete denture. The term “hybrid” implies a combination of a metal framework with a complete denture (prefabricated resin teeth and heat‐polymerized resin). The term “high‐water” refers to the design of this prosthesis using long standard abutments with several millimeters of space between the prosthesis and the underlying mucosa…

Hybrid implant
An endosseous, root‐form dental implant, with different surface geometries or textures at different levels.
