From implant placement to the crown — what are the stages of prosthetic treatment?

13 July From implant placement to the crown — what are the stages of prosthetic treatment?

The process from the placement of a dental implant to the fitting of a prosthetic crown involves several stages. The healing period is a crucial stage. The crown is not fitted immediately after the surgical procedure. The implant needs time to stabilise within the tissue. Applying pressure too early can disrupt this process.

Why isn’t the crown fitted onto the implant straight away?

Once the artificial root has been inserted, the gum requires appropriate surgical treatment. The healing phase usually lasts between three and six months. During this time, the implant remains hidden within the bone and is not used for chewing.

The healing process requires time and a calm biological environment. Bone tissue needs specific conditions to form strong structures around the thread. Even the slightest mechanical forces can disrupt the formation of new bone. For this reason, a tried-and-tested two-stage approach is most commonly used in dental practices.

What is osseointegration and how do we assess it?

Osteointegration is a phenomenon in which the bone fuses directly to the surface of the titanium component. Integration takes place at the microscopic level. The surface of the implant has a microporous structure, into which the body’s cells gradually penetrate.

The dentist checks this stage during scheduled follow-up appointments. At the Smile Clinic in Łódź, we use a clinical stability test for this purpose. Specialised equipment measures the resonance frequency and allows us to safely check the implant’s stability. This diagnostic procedure always precedes the start of prosthetic work.

How do imaging studies help with prosthetic planning?

Radiological diagnostics enable a precise assessment of the three-dimensional position of the implant. CBCT computed tomography provides a complete model of the patient’s bones. This image highlights the anatomical structures, including the floor of the maxillary sinus and the course of the nerves.

A panoramic X-ray complements the assessment of tissue density in the area under examination. At our clinic, this is a routine procedure carried out before taking impressions. The three-dimensional image helps the dental technician to precisely align the titanium abutment with the implant axis.

What is the process from implant placement to the crown?

Once the healing period is complete, the way is clear for the final restoration of the bite. The prosthetic procedure involves at least two visits to the dentist’s surgery.

Standard timetable for the proceedings:

• Exposure of the implant and tightening the forming screw for about two weeks.
• Taking an analogue impression or a digital intraoral scan.
• Fabrication of a custom abutment and restoration in the laboratory.
• Try-in, checking the occlusal conditions and final cementation of the restoration.

Impressions are taken using special transfer trays. The technician then digitally designs the shape of the future tooth. The restoration can be screwed directly onto the titanium abutment or permanently cemented in place using a special cement.

When is a temporary crown fitted on an implant?

A temporary solution is most commonly used during treatment of the anterior segment. A crown like this preserves the aesthetics of the smile whilst the bone heals. It also helps to shape the natural gum line around the developing tooth.

The decision to carry out this type of reconstruction depends on the assessment of the implant’s stability on the day of the procedure.

Feature	Temporary crown	The Final Crown
The moment of settling	Initial healing time	Following complete osseointegration
Main function	Aesthetics and gum contouring	Full chewing load
Material	Composite or advanced acrylic	Ceramics, zirconium oxide

In the lateral segments of the arch, the operated area is usually completely unloaded. This ensures safe conditions for the preparation of a permanent restoration.

What might delay the final fitting of the crown?

Soft tissue problems are the main cause of schedule delays. Inflammation of the gums means that prosthetic work must be postponed until the infection has cleared up. Daily oral hygiene remains just as important for the course of treatment.

The rate of healing slows down in the presence of comorbidities, such as uncontrolled diabetes. Smoking drastically reduces blood flow to the oral mucosa. Uncontrolled teeth clenching requires prior regulation of muscle tone. The dentist will only commence the prosthetic phase once these factors have been stabilised.

What can you expect once your prosthetic treatment is complete?

Daily oral hygiene directly affects the longevity of the restoration. The patient uses interdental brushes and an oral irrigator to clean hard-to-reach areas below the gum line.

Properly prepared implant-supported crowns They restore chewing function and provide physiological support for the lips and cheeks. However, the facial muscles must adapt to the new spatial conditions. The wearer of such a prosthesis is required to attend regular check-ups. This allows the dentist to systematically assess the stability of the titanium component and the health of the surrounding bone.

The implant-supported restoration process requires time for healing and osseointegration, usually lasting 3–6 months. Success depends on stability checks, X-ray and CBCT scans, as well as the condition of the gums and oral hygiene. The crown may be temporary or permanent, depending on the stability of the implant and occlusal conditions.

FAQ

Why isn’t the crown fitted onto the implant straight after the procedure?

An implant needs time to fuse with the bone and become stable. Applying pressure too early can disrupt osseointegration and compromise the outcome of the treatment. The healing phase is therefore essential before the final crown is fitted.

How does a dentist check whether an implant is ready for a crown?

The stability of the implant is assessed during follow-up appointments and through imaging tests. MRI stability measurements and a clinical assessment of the tissues surrounding the implant are also helpful. Only once proper osseointegration has been confirmed can the prosthetic phase begin.

What role does CBCT play in planning a crown on an implant?

CBCT imaging shows the three-dimensional position of the implant and the surrounding anatomical structures. It facilitates the assessment of the implant axis, the distance from nerves and sinuses, and the selection of the abutment and future crown. This allows the prosthetic stage to be planned more safely and accurately.

When is a temporary crown fitted on an implant?

A temporary crown is used when the implant is sufficiently stable and the priority is aesthetics and the shape of the gum. This most commonly applies to the anterior region. In the posterior regions, it is usually standard practice to wait for full healing before fitting the final crown.

What might delay the fitting of a crown onto an implant?

Delays can be caused by gum inflammation, poor oral hygiene, smoking, uncontrolled diabetes and clenching the teeth too hard. The bite force and the general condition of the soft tissues are also important factors. In such situations, the dentist first stabilises the condition before completing the treatment.
