What Is Cementation?

Cementation is the process in dentistry where fixed prostheses are permanently attached to teeth or implants using special dental adhesives. This method prevents the prosthesis from moving in the mouth and ensures long-term secure use. The adhesives used during cementation are biocompatible, helping to protect both teeth and gum health.

This procedure is applied only to fixed prostheses. Removable prostheses do not require cementation because they can be taken out by the patient. However, some implant-supported hybrid prostheses may combine both fixed and removable features, and in such cases, cementation can be applied using specialized techniques.

Purpose and Importance of Cementation

The main purpose of cementation is to prevent the prosthesis from moving, ensuring safe use both functionally and aesthetically. Chewing forces are transmitted evenly to the teeth, and proper adaptation of the prosthesis to the gums helps maintain gum health.

Incorrect cementation can lead to:

  • Prosthesis instability

  • Gum inflammation

  • Tooth decay

  • Complications around implants

Therefore, cementation must always be performed by a qualified dentist, under sterile conditions, and with the appropriate materials.

Cementation in Fixed Prostheses

Cementation is one of the most critical steps in fixed prosthesis treatment. The procedure typically involves:

  • Cleaning and drying the tooth or implant surface

  • Inspecting the inner surface of the prosthesis and making adjustments if needed

  • Applying special dental cements (adhesives) inside the prosthesis

  • Placing the prosthesis onto the tooth and seating it with controlled pressure

  • Removing excess cement to prevent gum irritation

Types of cements used for fixed prostheses include:

  • Permanent cements: Provide long-term stability

  • Temporary cements: Used for trial periods

  • Resin-based cements: Offer strong adhesion and durability

Cementation in Removable Prostheses

Removable prostheses generally do not require cementation, as they can be inserted and removed by the patient. However, in some special cases, particularly with implant-supported removable prostheses, hybrid systems may be used.

In these systems, part of the prosthesis is fixed to implants using cementation, while the other part remains removable. This improves prosthesis retention while still allowing the patient to remove it for cleaning.

Advantages of Cementation

  • Secures the prosthesis firmly in the mouth

  • Provides stability during chewing and speaking

  • Maintains natural and aesthetic appearance

  • Extends the lifespan of the prosthesis

With proper cementation, patients can use fixed prostheses just like their natural teeth in daily life.

Post-Cementation Care

After cementation, patients should follow these guidelines:

  • Avoid very hard foods for the first 24 hours

  • Maintain excellent oral hygiene, cleaning between teeth with special brushes

  • Attend regular dental check-ups

  • Contact your dentist immediately if you experience prosthesis movement, pain, or sensitivity

Proper care and regular monitoring help ensure that cementation remains effective for the long-term success of both fixed and hybrid prostheses.
