Problems solved by technology

This type of osteotome surgery can only lift the maxillary sinus floor in the range equal to the diameter of the end of the osteotome, so the lifting range of the maxillary sinus is limited, generally not exceeding 5mm, otherwise it will easily lead to damage to the sinus floor mucosa

Embodiment Construction

[0032] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0033] Such as figure 1 , figure 2 As shown, a maxillary sinus lifting osteotome includes a working end 1 and a handle 2. On the basis of retaining the end 0.3mm-1.5mm of the working end 1, a groove 4 is provided on the working end 1. The present invention The thickness reserved at the end of the middle working end 1 is preferably 0.5mm-1mm, and the thickness is moderate. During the operation, the sinus floor mucosa will not be damaged because the thickness is too thin, and the sinus floor mucosa will not be easily peeled off because the thickness is too thick. The groove 4 turns the working end 1 into a "semi-cylindrical" or "incompletely cylindrical" shape. On the premise of preparing an implant cavity with the same diameter, the osteotome can insert the sinus into the maxillary sinus. The bottom muco...

Abstract

The invention discloses a bone chisel for interior lifting of the maxillary sinus. The bone chisel comprises a working end and a handle, the working end is provided with a groove and used for stripping the sinus floor mucous membrane towards the periphery so that the maxillary sinus lifting range can be widened, the end face of the tail end of the working end is a plane, and the thickness of the tail end of the working end ranges from 0.3 mm to 1.5 mm. A cylindrical working end of a bone chisel in the prior art is changed into the half-cylindrical or incomplete-cylindrical working end by forming the groove in the working end; when the improved bone chisel is used for lifting of the maxillary sinus, the bone chisel can go deep into the maxillary sinus and then strip the sinus floor mucous membrane towards the periphery under the premise that an implant tooth cavity with the same diameter is prepared, the maxillary sinus bottom lifting range is widened, and therefore the lifting amplitude of the maxillary sinus is improved.

Description

technical field [0001] The invention relates to an osteotome, in particular to a maxillary sinus lifting osteotome. Background technique [0002] After the maxillary posterior teeth are missing, the lack of vertical bone mass due to the low floor of the maxillary sinus is a problem often encountered in implant surgery. [0003] The maxillary sinus floor lift is to lift the maxillary sinus mucosa from the sinus floor, and implant bone graft material between the sinus floor mucosa and the sinus floor bone to increase the height of the bone, so as to meet the needs of bone volume for dental implants. [0004] At present, the commonly used maxillary sinus floor lifting methods in clinical practice mainly include maxillary sinus internal lifting and maxillary sinus external lifting. Start at the center, go forward to the front slope, and open a window at a part with a length of about 15mm. Enter the maxillary sinus with the fenestration site, peel off the maxillary sinus floor ...
