Dental implants subjected to traumatic forces can survive. Cortical bone seems to provide a protective energy-absorbing mechanism in the collagen polymer that helps to prevent microcracking and fracture of bone. The collagen polymer has cross-linking bonds that break and absorb the energy of a traumatic impact so as not to cause damage to the main polymer(More)
This case report demonstrates the construction of a complete restoration of the dentition by the surgical placement of endosseous titanium implants that support a fixed prosthesis in each jaw. The positioning of the implants and teeth in the prostheses are important factors for a successful long-term result. Distribution of the occlusal biting forces over(More)
An incident of positional vertigo associated with osteotome technique for installation of multiple maxillary dental implants is reported. The symptoms resolved after 2 weeks with restricted physical activity and prohibition of lifting. There is a discussion of labyrinthine concussion and treatments. Suggestions for prevention are to use small sizes of(More)
A case of a delayed-onset post-operative altered sensation of the mental nerve is reported with speculations as to etiology. There is a discussion concerning intraoperative radiographs and osteotomy positioning. When postoperative altered sensation occurs, etiologic considerations should always include local anesthetic administration technique. The(More)
Dental implants can be displaced into the maxillary sinus. Retrieval by endoscopic or Caldwell-Luc techniques have been previously reported. A modified Caldwell-Luc technique is presented here, where a small round lateral osseous window is created. A plastic surgical aspirator tip is cut and modified to fit tightly into the access window. The sinus is(More)
There are 3 arteries that supply the maxillary sinus (i.e., the posterior superior alveolar, infraorbital, and posterior lateral nasal arteries), any of which may be encountered during lateral approach sinus elevation surgery. These arteries are ultimate branches of the maxillary artery. Although it has not been reported, there is a theoretical potential(More)
Penetration of the mandibular cortex during dental implant surgery may damage 3 important arteries and could lead to life-threatening circumstances. To lessen the likelihood of lateral angulations and cortical perforations, dental implants of less than 14 mm may be considered for the mandible. The courses of the inferior alveolar, facial, and lingual(More)
After dental implants are manufactured there can be a loss of biological activity that may be reactivated by exposure to ultraviolet (UV) radiation, that is, photofunctionalization. The titanium surface is energy conditioned by UV radiation. This imparts a slight positive surface energy and hydrophilicity to the titanium dental implant surface. This(More)
