Interchangeable Guide in Ridge Splitting Flapless Technique for Implant Placement

Fabrication of interchangeable surgical guide stent:

• Optical scanning of the dental casts was done using Ceramill map 400
• The treatment plan and the surgical stent were designed using Mimics Innovation Suite 19 ™ software
• Series of creating and designing special 3D virtual guide slits and boxes that can accommodate and precisely fit the tools used for the ridge splitting technique.

An informed consent is taken from all the patients

I. Presurgical phase:

1. Proper dental and medical history.
2. Scaling and oral hygiene measurements.
3. Clinical examination.
4. Radiographic examination. Clinical bucco-lingual measurements was done using calipers to ensure the patients would meet our initial inclusion criteria prior to further investigations.

III. Fabrication of interchangeable surgical guide stent from primary impression:

1. Optical scanning of the dental casts was done using Ceramill map 400
2. surgical stent was designed using Mimics Innovation Suite 19 ™ software.
3. Series of creating and designing special 3D virtual guide slits and boxes that can accommodate and precisely fit the tools used for the ridge splitting technique.

All patients will be operated under local anesthesia, stent was placed on ridge and adapted well after disinfection osteotomy was done using piezotome splitting tips Implant-insertion was started immediately

Visual Analouge Scale (VAS) 0=no pain

1. mild pain; it is easily tolerated
2. moderate pain; it is causing discomfort but bearable.
3. severe pain; it is causing discomfort, hardly tolerated and unbearable.
