Abstract
A dental membrane that is used with a patient having insufficient bone at a surgical site during a ridge augmentation. The dental membrane includes a first layer and a second layer. The first layer is cortical bone or formed from artificial bone materials to have characteristics of cortical bone. The second layer is cancellous bone or formed from artificial bone materials to have characteristics of cancellous bone.
Claims20
A dental membrane, comprising:
- a first layer having a first composition, the first composition comprising one or more of cortical bone and an artificial bone material that has characteristics of cortical bone;
- and
- a second layer having a second composition, the second composition comprising one or more of cancellous bone and an artificial bone material that has characteristics of cancellous bone, wherein the first layer is coupled to the second layer, wherein the first composition is different from the second composition, and wherein a first porosity of the first layer is less than a second porosity of the second layer and/or a first age pore diameter of the first layer is smaller than a second average pore diameter of the second layer.
A method of forming a dental membrane, the method comprising:
- obtaining a first layer comprising predominantly cortical bone;
- obtaining a second layer comprising predominantly cancellous bone;
- and
- coupling the first layer to the second layer, wherein a first composition of the first layer is different than a second composition of the second layer, wherein a first porosity of the first layer is less than a second porosity of the second layer, and wherein an average pore size of the first layer is less than an average pore size of the second layer.

A dental membrane, comprising:
- a first layer being formed from cortical bone;
- and
- a second layer being formed from cancellous bone, the first and second layers having different compositions,
- wherein the first layer is coupled to the second layer with a biocompatible adhesive, wherein the first layer and the second layer form an arc and the first layer defines an outer surface of the arc and the second layer defines an inner surface of the arc, and wherein the first layer has a thickness and a porosity less than a thickness and a porosity of the second layer.
