All-on-4 Implantation in Vilnius: Fixed Prosthesis on Four Implants

All-on-4 concept is revolutionary method for complete edentulous jaw restoration using fixed prosthesis that secured only on four strategically positioned implants. In our clinic, we perform All-on-4 implantation according to original Nobel Biocare protocol allowing patient to receive fixed teeth within one day. Method allows avoiding complex and expensive bone augmentation procedures, shortening treatment time, reducing cost compared to traditional implantation. Patient comes to clinic in morning without teeth or with teeth not subject to preservation, leaves in evening with new fixed smile.

We apply All-on-4 methodology for complete rehabilitation of patients with absence of all teeth or teeth not subject to preservation. Original Nobel Biocare or Straumann system implants used, specially created for this protocol. Our specialists have official All-on-4 training and certificates, carefully follow original protocol requirements. We ensure maximum planning precision using computed tomography and surgical templates, guaranteeing result predictability and longevity.

All-on-4 Technology Principle

Concept based on installing four implants in certain positions with optimal tilt angles. Two front implants installed vertically in central teeth zone, two lateral - tilted 30-45 degrees angle backward in molar teeth zone. In our clinic, we carefully plan each implant position, angle, depth using 3D software to achieve optimal bone utilization and stability.

Tilted lateral implants positioning has several advantages. Implant contact area with bone increases, ensuring better primary stability. Our specialists note that tilted screwed implants allow avoiding sinuses in upper jaw and nerve in lower jaw, using best bone regions. Also tilt allows using longer implants, which increases bone contact and stability.

Bridge prosthesis of 10-12 artificial teeth attached to four implants, completely restoring dental arch. Prosthesis manufactured from quality materials - acrylic with titanium frame, zirconia or hybrid composites. In our dentistry, we offer various prosthesis options depending on patient budget and aesthetic preferences. Temporary prosthesis placed on operation day, permanent - after 3-6 months osseointegration.

All-on-4 Method Advantages

Main protocol advantage - ability to receive fixed teeth in one day. In morning patient comes to clinic without teeth or with teeth subject to removal, in evening leaves with new fixed prosthesis allowing chewing, talking, smiling. In our clinic, this highly valued by patients - no need to walk without teeth or with uncomfortable removable constructions during healing period. This significantly improves psychological comfort, social life, self-confidence.

Technology often does not require bone grafting due to special implant positioning. This eliminates additional surgical interventions, shortens treatment time, reduces cost, decreases complication risk. Our specialists note that even with significant bone atrophy, tilted implants use allows utilizing remaining bone efficiently. Only very rarely additional bone augmentation procedures needed.

All-on-4 cost significantly lower than separate implant screwing for each missing tooth. At same time, patient receives full-fledged fixed construction allowing normal chewing of all food products. In our dentistry, one jaw All-on-4 cost usually 2-3 times less than traditional implantation with 8-10 implants. This makes method accessible to wider patient range.

Diagnosis and Planning

All-on-4 implantation success begins with detailed diagnosis. Computed tomography of both jaws mandatory, providing three-dimensional bone structure, sinuses, nerves images. In our clinic, we use latest tomographic devices with minimal radiation dose and highest image quality. Tomography allows accurately assessing bone quantity, quality, anatomical structures position.

Based on tomography data, virtual model created in special dental implantation planning program. Surgeon determines optimal implant positions and angles for each implant. Our specialists carefully plan to maximally utilize available bone, avoid sinuses and nerves, ensure uniform load distribution. Virtual planning allows seeing final result before operation.

According to planning results, surgical template manufactured - special cap with guiding openings that placed on jaw during operation. Template ensures precise implant screwing exactly where planned, with required angles and depths. In our dentistry, we use templates for all All-on-4 cases, minimizing errors, ensuring predictability. Template manufactured by 3D printing according to virtual model.

Operation Course

All-on-4 operation in our clinic performed within one day. Patient comes in morning on empty stomach. Can use local anesthesia or sedation depending on patient preferences and emotional state. Our specialists recommend sedation - allows patient feel completely calm, not remember operation, while being conscious and cooperating with doctor. During sedation, patient feels no pain, fear, discomfort.

If residual teeth present, surgeon first removes them. Then with surgical template precisely positions drills and forms openings for four implants. In our dentistry, we use special All-on-4 implantation kits with all necessary instruments. Drills form openings at required angles, precisely according to plan. Throughout process, constantly cool tissue with physiological solution to avoid overheating.

Four implants screwed in - two vertical in front, two tilted at sides. Surgeon carefully checks primary stability - implants must be firmly screwed. Our specialists note that for experienced surgeon, All-on-4 operation takes 1.5-2 hours for one jaw. Multi-unit abutments screwed onto implants - special connection elements allowing compensating implant angle differences and creating uniform prosthetic level.

Temporary Prosthetics

After implant screwing, temporary prosthetics performed same day. In our clinic, temporary prosthesis usually manufactured in advance according to virtual plan and patient impressions. This acrylic base with plastic or composite teeth connected with titanium or chrome-cobalt frame. Prosthesis secured to implants with screws through special openings.

Temporary prosthesis has slightly reduced occlusal contacts with opposing teeth not to overload just screwed implants. However, allows normal soft food chewing, talking, smiling. Our specialists adjust prosthesis immediately on operation day, correct occlusion, ensure comfort. Patient leaves with teeth, can return to normal life.

First 2-3 months very important to follow gentle diet - soft food, avoid hard, sticky, very hot food. In our dentistry, we provide detailed nutrition recommendations during temporary prosthetics period. Also hygiene important - brush teeth gently, rinse mouth with antiseptic. Regular control examinations every 1-2 weeks first months.

Permanent Prosthetics

After 3-6 months osseointegration - when implants fused with bone - permanent prosthetics stage begins. Temporary prosthesis removed, precise impressions taken or digital scanning of implant positions. In our clinic, we use both methods - traditional impressions with special implant transfers or intraoral 3D scanner. Digital scanning allows achieving greater precision and patient comfort.

Data sent to laboratory where technicians manufacture permanent prosthesis. Several permanent prosthesis options available depending on budget and preferences. Economy option - acrylic base with composite teeth on titanium frame. Medium - hybrid composite or zirconia-acrylic construction. Premium - zirconia or all-ceramic construction with individually manufactured ceramic teeth. In our dentistry, we help choose optimal option.

Permanent prosthesis secured to implants with screws, allowing removal for service. This convenient - if needed, doctor can remove prosthesis for implant cleaning, repair, replacement. Patient cannot remove prosthesis themselves - this fixed construction that holds firmly. Our specialists carefully check occlusion, aesthetics, phonetics, adjust if needed. Patient receives detailed care recommendations.

Care and Longevity

All-on-4 prosthesis care in our clinic includes regular home hygiene and professional cleaning in clinic. At home, need to brush prosthesis with special soft brush twice daily, use interdental brushes or waterjet for implant zones cleaning. Important to clean not only teeth but also prosthesis base bottom where it touches mucosa. Our specialists teach patients proper hygiene techniques.

Professional teeth cleaning in clinic mandatory every 3-6 months. In our dentistry, we use special instruments and pastes safe for implants. Control X-ray images taken for bone condition monitoring around implants. Prosthesis construction condition checked - screws, joints, teeth. Timely notice problems - loosened screws, teeth chipping - and eliminate them.

All-on-4 implants longevity very good with proper care. In our clinic, screwed implants have over 95-98% survival rate over 10 years. This means vast majority of implants serve long without problems. Prosthesis constructions usually serve 10-15 years, after which they may need replacement or renovation. Our specialists ensure long-term patient support, help maintain All-on-4 in optimal condition.

Complications and Their Prevention

Although All-on-4 is very predictable method, complications possible. One possible - implant non-integration, occurring in 1-2% cases. Reasons - excessive load too early, infection, insufficient bone quality, smoking. In our clinic, we minimize risk with careful planning, using surgical templates, controlling load during temporary prosthetics period. With implant non-integration, remove it and screw new one after healing.

Another possible complication - prosthesis construction problems - screw loosening, teeth chipping, base fracture. This most often occurs with excessive loads, one-sided chewing, bruxism. Our specialists carefully check occlusion, ensure uniform load distribution. For patients with bruxism, recommend night protective cap. In most cases, construction problems easily fixed - screw replacement, teeth repair.

Rarely peri-implantitis possible - inflammation of tissues around implant. Reasons - poor hygiene, plaque accumulation, smoking. Prevention - good home hygiene, regular professional cleaning in our dentistry. Our doctors monitor peri-implantitis signs - gum redness, bleeding, depth - and timely treat.

All-on-4 vs Traditional Removable Dentures

Comparing All-on-4 with traditional removable dentures, advantages obvious. Removable dentures hold on gums with vacuum or adhesives, often slip, cause discomfort, interfere with speech, chewing. In our clinic, patients with removable dentures complain of limited chewing function, discomfort, social inconvenience. Need to remove dentures in evenings for cleaning, cannot chew hard food.

All-on-4 is fixed construction that holds firmly on implants. It does not slip, does not interfere with talking, allows chewing all food products like with natural teeth. Our specialists note that patients after All-on-4 receive significantly better life quality - self-confidence, social activity, nutrition possibilities. Implants stimulate bone, prevent atrophy, which occurs with removable dentures.

All-on-4 cost higher initially than removable dentures, but in long-term perspective very similar. Removable dentures require periodic replacement every 3-5 years due to bone atrophy and denture wear. Also need adhesives, cleaning agents. In our dentistry, we explain to patients that All-on-4 investment pays off year after year with better function, comfort, health.

All-on-4 vs All-on-6

Besides All-on-4, there is All-on-6 concept - entire jaw restoration on six implants instead of four. Two additional implants screwed between front and lateral implants. This gives greater construction stability, better load distribution. In our clinic, we recommend All-on-6 for certain cases.

All-on-6 indications - difficult bone quality in lower jaw, large chewing loads for patients with strong muscles, long dental arches requiring more support points. All-on-6 also more reliable with one implant non-integration - 5 functioning implants remain, usually sufficient for prosthesis support. Our specialists individually assess each patient situation and recommend All-on-4 or All-on-6.

All-on-6 cost slightly higher than All-on-4 due to two additional implants, but stability advantage may be worth in certain cases. In our dentistry, for upper jaw often All-on-4 sufficient due to better bone quality, for lower may be better All-on-6 due to more intensive loads.

Frequently Asked Questions

Is All-on-4 safe method?

Yes, All-on-4 is very safe and predictable method when performed according to original protocol by experienced surgeons. In our clinic, we follow all Nobel Biocare requirements, use surgical templates for precision, carefully plan each case. Concept used worldwide for more than 20 years, millions of patients successfully treated. Clinical studies show highest survival rates and patient satisfaction.

Can chew everything with All-on-4?

After osseointegration and permanent prosthetics with All-on-4, can chew most food products including hard meat, vegetables, bread. Our specialists recommend avoiding only very hard products - nut shells, ice chewing, bone chewing. Also useful to chew on both sides for uniform load. Many patients report that chewing function with All-on-4 significantly better than with removable dentures, close to natural teeth.

How long does healing take?

First healing stage - 1-2 weeks when swelling decreases, discomfort, sutures removed. But complete osseointegration - implant fusion with bone - takes 3-6 months. During this period, temporary prosthesis used allowing normal functioning. In our clinic, we monitor healing with control examinations, ensure everything proceeding normally. After osseointegration, permanent prosthesis placed.

How much does All-on-4 cost?

All-on-4 cost in our clinic for one jaw with original Nobel Biocare implants and temporary prosthesis usually 7000-10000 Eur. Permanent prosthesis - additionally 3000-8000 Eur depending on material choice. Total treatment for one jaw - 10000-15000 Eur. This investment in quality, long-term solution. In our dentistry, we offer various payment options, transparent prices, detailed estimate.
