It is a surgical procedure in which the membrane in maxillary sinus is lifted from the bottom of the sinus and the newly formed space is filled up with bone replacement. This procedure is performed if bone in the area of back teeth in the upper jaw has insufficient volume for insertion of a tooth implant. This procedure is used in case of missing bones most frequently since it has the best success rate. There are two types of sinus lifting:
1. open sinus lifting –access to the membrane of jaw cavity is made via the lateral bone wall of this cavity
2. closed sinus lifting –access to jaw cavity and the membrane which lines it, is realized via the hole prepared for the future insertion of the implant. This procedure has one disadvantage – it is performed blind and in case it fails, open sinus lifting must be conducted anyhow.
Augmentation of bone or soft tissues
In implant dentistry this term referrs to magnification of bone or soft tissue (jaw) volume before, during, or after the actual insertion of the implant. The aim of all these precedures is to achieve a long-term functional and esthetic stability and long-term satisfaction of each patient.
It is a procedure in which a thin alveolar bone is augmented or widened. If performed by an experienced implantologist, it has a high success rate. It is used in case a thin type of implant (e. g. mini implant) cannot be used due to too thin bone or in case such implant would have a low chance to function properly in the areas of increased loading.
