HOWEVER, A GOOD PRACTICE IS TO PLACE THE RESPECTIVE DENTAL IMPLANT ACCURATELY IN THE FIRST PLACE. BUT SOMETIMES DUE TO A LACK OF PRECISION OR EQUIPMENT ISSUES, THE ALIGNMENTOFTHEDENTALIMPLANTIS DISTURBED. IN SUCH A SCENARIO, MULTI-UNIT ABUTMENTS COME IN HANDY.

#RULE1 MULTI-UNIT ABUTMENTS ARE PRONE TO DAMAGEBECAUSEOFSHEARINGFORCES. TO ENSURE THEY DON'T GET DAMAGED, PROPERLY DESIGNING THEM IS ESSENTIAL. IT MEANS THAT THE SHAPE AND SIZE OF THE ABUTMENTS SHOULD BE APPROPRIATETOKEEPTHEMSAFE. DURING THE PROCESS, WHEN OCCLUSAL FORCESAREAPPLIEDTOTHEABUTMENTS, THEY CAN BREAK OR CRACK, IF THE DESIGNISNOTPROPER.FORTHISREASON, IT IS CRUCIAL TO MAKE ABUTMENTS RESISTANT TO DESTRUCTIVE FORCES TO AVOIDANYISSUESDURINGTHEPROCESS.
#RULE2 IT IS THE RESPONSIBILITY OF THE LAB TECHNICIAN TO TELL THE SURGEON ABOUT THE RIGHT LINGUAL LOCATION. WITH THE HELP OF THIS LOCATION, THE DENTAL EXPERT CAN EASILY GET TO KNOW ABOUT THE PLACE AT WHICH THE LINGUALSCREWISPRESENT.ASARESULT, CONTINUINGTHEPROCESSWITHOUTANY MISTAKESBECOMESEASY. MOREOVER, THEY ALSO HAVE TO CONSIDER THE POSITION OF THE TONGUE DURING THE PROCEDURE. FURTHERMORE, THE SURGEONS HAVE TO TAKE THE LINGUAL SURFACES OF MANDIBULAR PREMOLARS AND MAXILLARY PREMOLARS INTO ACCOUNT. BY GETTING THE REQUIRED GUIDANCE FROM THE LAB TECHNICIAN, THE TASK OF THE SURGEON BECOMESEASY.
THE RESPECTIVE DENTAL EXPERT SHOULD HAVE A DETAILED IDEA ABOUT THE FINAL FORM OF THE PROSTHESIS. FOR THIS REASON,THEFINALSHAPEMUSTBECLEAR IN THEIR MINDS, BEFORE THEY START THE PROCESS. THERE ARE TWO WAYS OF ESTIMATING THE FINAL LOOK OF THE PROSTHESIS WELL IN ADVANCE, WHICH ARE CASTING WAX PATTERNS AND VIRTUALSTRUCTUREONACOMPUTER. WAX CASTING IS THE TRADITIONAL METHOD THAT IS USED BY DENTAL PRACTITIONERS FOR YEARS. ON THE OTHER HAND, GENERATING THE STRUCTURE THROUGH THE COMPUTER IS A NEWER PRACTICE. HOWEVER, GOOD ACCURACY CAN BE ACHIEVED IN THE COMPUTER METHOD, COMPARED TO THE WAXONE.
