Abstract: The present invention discloses a synthetic polymer tooth replacement for replacing a missing tooth. The synthetic tooth replacement is a periodontic implant suitable for natural and reconstructed periodontic in the geometric/topographic construct similar to that of a natural tooth's dentin below the gumline. The synthetic polymer tooth replacement is made of a composition comprising a moldable resin and weighted particular additives. The replacement is formed by centrifuging the composition and pouring into a mold. The mold is customized to the recipients missing tooth, resulting in a replacement that has an exterior that is configured to bow out over a period of time, such that when the partially cured replacement is placed in a recipient's dental cavity, the replacement locks into the place while fully curing over a period of time. The advantages are the natural feel and noninvasive nature of the polymer dentin, which does not disturb the natural state of the dentin cavities.

Abstract: Phase change material microcapsules are obtained using a PMMA prepolymer and an organic-solvent free synthesis process. A polymer monomer and an initiator are subject to pre-polymerization in a water bath to form Polymethyl methacrylate (PMMA) prepolymer which is then prepared to be a stabilizer aqueous solution. A phase change material is added to the stabilizer aqueous solution and liquefied in advance, and stirred to form an emulsion by a homogenizing mixer. A starting agent, a cross-linking agent and a Polymethyl methacrylate methyl ester prepolymer are added to the emulsion containing the phase-change material. The emulsion is further stirred by the homogenizing mixer for micro-emulsification which then aggregates in water bath.
