Correct digital response to Dental Implant Surgery

 

Thescrew retained prosthesis is to connect the upper prosthesis to the abutmentusing only screw. 

However, the analog screw retained prosthesis is a complexprosthesis that requires fairly high level of technique, 

and the cost and timerequired to manufacture is also high, so it is not widely used.

 

However,with the recent development of intra-oral scanner and CAD-CAM technology, CADCAM abutment and zirconia implant prosthetic manufacturing are preferred. 

Whatshould be noted here is that the remaining cement in the subgingival region wherethe cement was not removed due to 

the bonding process between the abutment andthe upper crown using cement may cause peri-implantitis later.

 

It is a prosthetic form using digitaltechnology that allows you to select an implant with a design suitable for thecase; 

analyze and install the implant using a surgical guide at the appropriatephysiological and prosthetic position; and retrieve it at any time.

 

Sincethe process of taking impressions and prosthesis manufacturing becomes simpler dueto the introduction of an intraoral scanner, 

it is possible to minimize themanufacturing error of the prosthesis in comparison to the existing prosthesis manufacturingmethod.

Thisadvantage significantly reduces the prosthetic re-manufacturing rate and thenumber of hospital visits and chair time, significantly raising patientsatisfaction.

In addition, it is a prosthesis that can beattached and removed at any time, thus repair and maintenance are moreconvenient.

 

 

A. Crown angle screw channel machining tool usingvarious tools/Improvedaesthetics due to anterior angle machining

B.One-body zirconia interface parts can be machined using a flat tool

C.Precision machining using 0.3mm tools exclusively for zirconia

D.Detailed labial side machining using C-TYPE JIG

 

 

 

The screw type prosthesis is healthier in the surrounding tissuethan the cement type prosthesis.

Thisis especially true in the case of multiple implants. In addition, since the cementremnant may always remain and cannot be completely removed under some circumstances, 

there is the possibility of peri-implantitis.

 

The prosthesis can be easily removed and re-attached at anytime.

Sincethe fixing power of cement is not consistent, there are many times when thepatient feel discomfort because it cannot be removed when it is wanted and itfalls out when it is not wanted.

Inaddition, repair and management of prosthesis are essential (e.g. correction ofthe proximal surface, porcelain fracture, and contour adjustment, etc.), whichis especially important when multiple implants are connected.

 

Early detection and easy treatment of peri-implantitis

Sinceperi-implantitis may occur at any time, early detection and treatment is themost critical strategy. 

To that end, the removal and re-attachment ofprosthesis are essential.

 

Removal and re-attachment of prosthesis are essential for thetreatment of adjacent teeth.

If the implant is removed for proximal caries, rootcanal treatment, or crown treatment on adjacent teeth, it makes it easy totreat. In particular, 

it is a great advantage to be able to bridge with theexisting implant when adjacent teethare extracted.

 

As the number of prostheses and of cases increases, problemsincrease, which makes the retrievability become more important. 

The chair timeis much reduced and the patient's discomfort is reduced in the setting process.

Sincethe prosthesis is only attached to the patient when it is in a completed state,only proximal treatment or occlusal adjustment is required, 

which allows forcomplete treatment in a short time. In particular, the discomfort felt by thepatient during attachment is way less than that felt from the cement typeprosthesis.
