There are different techniques for the sinus augmentation. The two different ways of sinus floor elevation known as: a) Lateral approach (external technique) as a one or two step procedure as direct method. External technique allows for a greater amount of bone augmentation to the atrophic maxilla but requires a larger surgical access. b) Osteotome technique with a crestal approach (internal technique) as indirect method. The internal technique is considered to be a less invasive alternative to the external method to increase the volume of bone in the posterior maxilla. An ideal maxillary sinus bone-grafting material should provide biologic stability, ensure volume maintenance, and allow the occurrence of new bone infiltration and bone remodeling. Over time, bone-grafting materials and implants should achieve osseo integration. After the restoration of the upper part of the implant has been completed, there should be no bone loss and the materials should be stable; there should be a predictable success rate. The most common intraoperative complication during the sinus floor augmentation is perforationthe Schneiderian membrane. The literature have been reported of perforation rates of 14-56% (Ardekian et al., 2006; Pikos, 2008, Proussaefs et al., 2004; Shlomi et al., 2004). This kind of event is often predictable, but not avoidable, since it is strictly associated to anatomo-pathological predispositions.
The perforation of the maxillary sinus mucosa during lateral sinus lift can be repaired with SinossFleece completed with the augmentation procedure and bone replacemant material respective collagen membrane e. g. SinossGraft and SinossMem, without breaking the treatment.
1. Lateral approach (external technique)
Lateral Sinus Lift is one of the most widely used augmentation procedures. It enables to make an implant in the dorsal parts of the maxilla, where the bone often has poor quality and is reduced by the extended maxillary sinus.
2. Osteotome technique with a crestal approach (internal technique) osteotome technique is a less-invasive surgery with smaller flap design and a less
The osteotome technique is a less-invasive surgery with smaller flap design and a less extensive osteotomy. Therefore, there is less chance of postoperative complications and morbidity, and patient acceptance for surgery is greatly increased.
novadento provides a variety of suitable product solutions for various techniques.
The use of a collagen membrane such as SinossMem increases implant survival rate significantly.
SinossFleece can also be used to protect or repair a perforated Schneiderian membrane during
surgery and healing.
