A method of forming dental products, such as dentures, denture relines, dental crowns, dental bridges and dental restorative materials, temporary crown, temporary bridge, provisional crown or provisional bridge, from two polymerizable paste compositions each having a complimentary component of a free radical catalyst system and a polymerizable acrylic compound. One of these paste compositions includes an oxidizing agent and a stabilizer and the other includes a reducing agent as components of a redox catalyst system for free radical polymerization. These paste compositions are mixed in a static mixer to form a polymerizing paste composition, which is then shaped into a dental prosthesis. A handheld mixing dispenser useful in carrying out this method, includes a static mixing conduit, and two containers enclosing the polymerizable paste compositions. The static mixing conduit encloses a static mixing member. The containers are adapted to be connected in fluid flow communication with the static mixing conduit. In the paste composition which includes the reducing agent a photoinitiator may be preferably included. Each container is sufficiently oxygen permeable to maintain inhibition of polymerization of the polymerizable paste composition therein for at least 12 months at 23.degree. C.
