Apical Restriction


It is the process of removing the cyst or infection at the end of the tooth root together with the lower part of the tooth root by 1/3.

Can apical resection surgery be applied to all teeth?


  • Apical resection surgery can be applied to all teeth, including large molars.
  • The area where the molars are located should be evaluated in detail for apical resection. Especially in the lower jaw, it will be healthier to shoot the tooth if it is thought that the nerve can be damaged during surgery.
  • In addition, the length of the tooth root is an important factor in the indication of apical resection. If the lower part of the tooth root of 1/3 is removed, if the length of the remaining tooth root will remain too short, it will be healthier to pull the tooth.

In which cases is apical resection surgery performed?

  • It is applied in cysts or infections that occur in the root of the tooth and do not pass through root canal treatment.
  • When performing root canal treatment, it is done in case the root tool breaks at the root end.
  • It is applied in cases where the root end of the canal treatment overflows.
  • It is applied for the pains that occur after root canal treatment.
  • As a result of trauma to the tooth, it is applied in cases where the tooth root is broken.
  • In cases where the tooth does not complete root development, if canal treatment is required, it is applied to close the root end of the tooth.
  • The root structure and shape of the tooth in apical resection is performed in cases where it does not allow root treatment.


How to perform apical resection?

  • Following anesthesia, an incision is performed on the gums and the gingival flap is removed.
  • The bone around the root end of the tooth is removed to some degree.
  • If the cyst is present at the root end, the cyst is removed from the bone in one piece.
  • The root tip of the tooth is cut off with the help of burs and corrected.
  • The part of the canal treatment at the root end is carved. The duct mouth is closed with special filling materials (MTA) to ensure sealing on it.
  • The cyst cavity is sterilized by washing with plenty of serum physiologically.
  • If large bone destruction has occurred in the cyst cavity, the socket is filled with bone grafts.
  • The apical resection process is completed by closing the soft tissue with the help of seams.

What should I pay attention to after apical resection surgery?

  • In order to avoid bleeding after the operation, cotton soft must be held on the area for about half an hour. Hot and hard food drinks should be avoided. Solid foods should not be eaten until the effect of anesthesia passes.
  • It is necessary to apply ice from the outside so that swelling does not occur after the operation. Ice is applied externally to an operation area at 24 hours and 10 minutes. This procedure should be applied mostly in cases where the bone is over-removed.
  • After apical resection, the prosthesis should not be applied to the tooth for 3-4 months, excessive force should not be given to the tooth.
  • Mild swelling and pain after apical resection is normal. You should use antibiotics, and painkillers, which your doctor prescribes. It is necessary to keep oral hygiene at the highest level with mouthwash and toothbrushing.


  • There is a risk of recurrence of infection after apical resection. In case of repetition; swelling, pain, and inflammation occur at the root of the tooth.
  • If infection occurs after apical resection surgery, the area should be opened again and the diseased tissue should be cleaned. The possibility of recurrence of infection can always be found.
  • Implant treatment, which has become widespread in today’s period, especially in these cases, of recurrent infections, is a good alternative treatment instead of the tooth. Because dental implants that are compatible with the body are placed in the place of the missing tooth, they meet all kinds of aesthetics and functions of the tooth, they are used in a healthy and successful way for very long periods of time.
